Causing 500 Internal Server errors

  • Hi gang! First off, let me say that I’ve enjoyed using your plugin (I replaced Yoast SEO with yours). However, in recently trying to diagnose problems with receiving 500 internal server errors, I disabled all plugins, and then activated them one-by-one to diagnose if it was a plugin causing the problem. I found three plugins that were causing the problems.

    1. Forminator (a forms plugin); problems occurred when activated, stopped when deactivated; solution: Deleted plugin
    2. Chaty (a press to call for mobile plugin); problems when active, stopped when deactivated; solution: deleted plugin
    3. Rank Math SEO (free version); I was really hoping this wouldn’t be another plugin causing the problem, but I noticed two things. The site edit pages and previews were slowed down considerably after re-activating the Rank Math plugin, and on the 4th attempt to preview a page, I received an internal server error. I then received several within 5 minutes, and after deactivating the plugin, I haven’t received any. I wound up deleting the plugin. I’m simply writing to let you know that (at least in my case) your plugin was caused 500 internal server errors.

    For information, the site I design is hosted by Hostgator on their Optimized WordPress Hosting Plan using 5.6, and with PHP 7.4 installed. 256 MB RAM, and 25 process limit. I have other plugins installed which could have created conflicts perhaps, but only three plugins caused the internal server errors, and unfortunately RankMath was one of them.

    Sorry…but I thought you might be interested.

    If I can be of any further help, please let me know.

  • Hello,

    Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.

    It seems to be working fine on our end.

    Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

    To determine that, please follow this troubleshooting guide:

    Only the site admin would know and your users won’t be affected by this troubleshooting.

    If the issue persists, please record a video screencast using a tool like Loom showing the troubleshooting and edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
    Sensitive Data Section

    It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

    You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

    Please do take a complete backup of your website before sharing the information with us.

    We really look forward to helping you.

    I’m not sure what you mean by “it seems to be working fine on our end?” I didn’t provide the domain that the problems were occurring on, and in my original post, I mentioned that as a result of the internal server errors when RankMath was activated, I simply deleted the plugin.

    Providing credentials for you to log into my wordpress installation and admin panel won’t help because the plugin is no longer installed. I was simply writing to you to let you know there may be some sort of issue with the plugin, not necessarily for help in fixing the problem. I’m also unwilling to disable or delete any other plugins, as they are necessary for the site to work as designed.

    If I’m misunderstanding something, please let me know.




    Thank you for your feedback, and I do apologize for any inconveniences due to that.

    When we mentioned that it works on our end, it normally indicates that our team have tested it with the other plugins that you have mentioned.

    Normally to allow Rank Math plugin to work properly we do recommend our users to run through the plugin requirements here:

    Also, to check if there any conflicts with other plugins here:

    In other cases, it could be something else, and if you still want us to find and fix the issue that is causing it, we would need temporary access.

    But thank you for letting us know and if you decide to use our plugin back and have issues in the future do let us know, and we will be happy to help.

    Looking forward to helping you.


    Guten Tag auch bei mir löst Rankmath Pro einen Serverausfall aus.
    Im Vordergrund läuft alles gut, aber im Admin Bereich ist alles ganz langsam bis der Server ausfällt. Sobald ich den Ordner vom Rankmath Pro umschreibe, funktioniert wieder alles.

    Meine Uberdachung,

    Vielen Dank, dass Sie diese Informationen beigesteuert haben. Ich bin froh, dass es nicht nur ich bin, der das Problem erlebt, wie in privaten E-Mails mit RankMath, sie versichern mir, dass es nichts mit ihrem Plugin zu tun hat. Auf ihren Rat hin habe ich Gestern Abend RankMath neu installiert, und innerhalb von zwei Minuten erhielt ich interne Serverfehler. Nach dem Deaktivieren keine Fehler mehr. Ich mag das Plugin wirklich, so hoffe ich, dass sie tatsächlich in es mehr schauen.

    In English:

    Thank you for contributing that information. I’m glad it’s not just me who’s experiencing the issue, as in private emails with RankMath, they assure me it has nothing to do with their plugin. On their advice, last night I reinstalled RankMath, and within two minutes, I received internal server errors. After disabling it, no more errors. I really like the plugin, so I hope they actually look into it more.


    Im also having problems with the plug-in (free and with pro is even worse) with very slow page loads on the backend. I have a really good VPS server.

    Hi Tiago!

    Thanks for the input! Yeah, in my original post, you can see where I mentioned that everything slowed down noticeably after activating the plugin. Hostgator’s tech support told me that’s a fairly common issue with all SEO plugins, although I’m not sure why? Maybe Rank Math’s support can explain that here?

    I’m also willing to deal with things being a bit slow IF I can get rid of the internal server errors. Rank Math seems to be the best SEO plugin on the market, so I’m really hoping we can figure out a way to get those errors to stop. Maybe their tech support can also offer a few ways to optimize its performance so it doesn’t slow the site down while editing, updating, and previewing.

    I’m glad you chimed in! Thanks!



    Sorry for the delay.

    Could you provide the error message in your error log from the date the error occurred for us to investigate further?

    You can add them in the designated Sensitive Data section:
    Sensitive Data Section

    It is completely secure, and only our support staff has access to that section.

    Thank you, and looking forward to helping you.


    I have updated the sensitive data as requested. Can you please check further?

    Thank you.


    Thank you for that additional information.

    We need to determine what exactly the error to investigate further. Please set WP_DEBUG & WP_DEBUG_LOG value to true in the wp-config.php file, activate the Rank Math plugin, and go to the page where you are getting the error. You can add the following 3 lines in the wp-config.php file:

    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_DISPLAY', false);
    define( 'WP_DEBUG_LOG', true );

    After adding this code, your site’s errors will get logged in the debug.log file, which you can then share with us. Also, a screenshot of the error logs in your admin-ajax.php where the Rank Math error occurs would be helpful.

    I hope that helps. Thank you, and looking forward to your update.


    Ich habe bei mir den Fehler gefunden. Es war das Plugin “SEO Optimized Images”
    vielleicht habt ihr das auch.

    Jetzt läuft alles ganz normal.


    We are glad you found the plugin causing the issue ?

    Do you have any further questions? If you do, please let us know.

    Thank you


    I didn’t quite understand your message. The plugin causing the issue is YOUR plugin. That’s why we’re trying to figure out why RankMath is causing 500 internal server errors. I added the debugging script that Reinelle suggested above to my wp-config.php file, but the actual debug.log file doesn’t show up in any of my directories. Online, it says to look in the wp-content directory, but it’s not there. So I took screenshots of a Query Monitor page which may be of use?

    I’ll post those in the private section.


    Meine Uberdachung,

    Above, he wrote: “I found the error. It was the plugin “SEO Optimized Images”
    maybe you have. Now everything is going normally.”

    My reply in English:

    Meine, I’m glad you solved your issue. I don’t have that plugin installed, and for now, there’s some kind of conflict with the RankMath plugin, as I only get the internal server errors when it’s activated. I’m glad you solved your problem though!! Congratulations! 🙂

    In German:

    Meine, ich bin froh, dass Sie Ihr Problem gelöst haben. Ich habe dieses Plugin nicht installiert, und im Moment gibt es eine Art Von Konflikt mit dem RankMath Plugin, da ich nur die internen Serverfehler bekomme, wenn es aktiviert ist. Ich bin froh, dass Sie Ihr Problem gelöst haben!! Herzlichen glückwunsch! 🙂



    Ohhhh…I think your message above was to Meine Underdachung, and not me. Sorry about that! Perhaps next time, if the poster is a commenter on original post (and not the original poster)…it might make sense to address that person so everyone knows who you’re replaying to. Just a suggestion. : )
