Php errors and opening the menu in the mobile version on the projects page

  • Resolved Sergey P.
    Rank Math free


    On my site
    After installing the Rank Math plug-in, a menu in the header no longer appears on the mobile device in the “projects” section.

    There were php errors on many pages of the site. Location: wp-content / plugins / seo-by-rank-math / includes / frontend / class-breadcrumbs.php: 143

    This probably increased the server load.

  • Hello,

    Thank you for getting in touch with us and sorry for any inconvenience caused.

    We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WP 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):

    We really look forward to helping you.


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

    Thank you.


    Thank you for contacting Rank Math today.

    I am afraid that I cannot reproduce any errors on the frontend or the backend of your site. The sub menu item also appears on mobile devices when testing on a desktop and mobile browser as shown below:

    Please let me know if I am missing something.

    Looking forward to helping you. Thank you.



    For errors, please pay attention to what your plugin creates. screenshots on the link

    Hi Sergey,

    Thanks for the follow up.

    It is likely that there is a conflict with one of your installed plugins that is causing this error on the frotend. Could you please perform the troubleshooting steps described on this page:

    Let us know how this goes. Thank you.

    Did according to the instructions. But I did not understand what the error was. If it’s easy for you, please test yourself. I am not a website developer. Therefore, it is difficult for me with this.

    But most likely problems with the topic itself.

    And yes, when installing Latespeed Cache or W3 Total cache, all internal pages except the main one give an error of 500.


    Thank you for the follow up.

    The error reported on the query monitor tab is stemming from a conflict with your theme’s breadcrumbs function. I would suggest that you reach out to the author of the theme so that they can advise further.
    The second issue does not appear to be related to Rank Math but it looks like there is a server configuration issue that is causing the 500 errors.
    Please edit your wp-config.php file and enable debugging and then check the errors that are will be logged on the debug log.

    Looking forward to helping you. Thank you.



    what problems do you mean in the wp-config.php file

    Hi Sergey,

    Thank you for the response.

    The problem is not within wp-config.php file, my recommendation was to edit this file to enable error logging on your site through adding the following values:

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

    You will then need to check the kind of errors that are reported on the following file:

    I hope this info helps. Thank you.


    Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.

    If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.

    Thank you.
