Fatal Error

  • Hi,

    I am using WP Ultimo for a WAAS system.
    This error started happening in the last few weeks.
    Whenever a user creates a new site after signing up, there is a critical error, and it’s not possible to login or the site is coprrupted.

    Error message in the sensitive data area:

  • Hello,

    Sorry for any inconvenience that might have been caused due to that.

    It seems like new tables are not getting created in the Database or some old plugin has left an incorrect entry.

    Please follow these steps to fix the issue:

    1. Take a complete backup of your website

    2. Install this plugin: https://wordpress.org/plugins/code-snippets/

    3. Head over to the Snippets menu in the left sidebar and click Add New
    add new snippet

    4. Give that post any name and copy the below code in the Code field

    add_action( 'init', function() {
    	delete_option( 'schema-ActionScheduler_StoreSchema' );
    } );

    5. Select ‘Only run in administration area’ option and click the Save and Activate button
    run only in admin area wordpress

    6. Open WordPress Dashboard in a new window

    7. Then deactivate recently created snippet from here
    disable snippet

    8. Then activate the Rank Math plugin again

    9. Please disable the Code Snippets plugin if you are not going to use it

    Here’s a video screencast:

    Please clear all the cache, including the server after following the above process.

    That should resolve the issue. Thank you.

    Is this to be done for all sites in the multisite network?


    Only the main site needs this operation done once.

    Do disable the plugin after executing the code and then activate Rank Math.

    Looking forward to helping you. Thank you.


    I followed the steps exactly as you mentioned, but I am still getting the same fatal error.

    Please advise.


    If that doesn’t help, we might need to take a closer look at the settings. Please 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):


    We really look forward to helping you. Thank you.

    Can I give you the network’s back up using All in One Migration?


    That won’t help as the process will become cumbersome.

    1. Please follow these steps to fix the issue:

    2. Please follow only the first 2 steps and clear your caches. The following steps mentioned in the article are for the advanced users.

    Here’s a video screencast:

    Please clear all the cache, including the server after following the above process.

    If that doesn’t help, then please add your WordPress & FTP login details so we can take a closer look.

    Looking forward to helping you. Thank you.


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

    Thank you.

    Updated the logins.

    Please note, this is my PRD network, with live sites and users.

    Another point,

    On deactivating Rank Math, the sites get created without any issues.


    Please take a complete backup of your site so we can debug and fix.

    Looking forward to helping you. Thank you.

    I have already taken a back up before doing the steps mentioned by you.

    However there are live users on the network, hence I mentioned it would be better if you download the back up from the all in one migration plugin.

    Please advise.


    Please create a staging site then and we can debug there.

    Looking forward to helping you. Thank you.

    I have a staging site, where I restored a back up 2 days ago.
    But the issue is not happening there. It is only happening in PRD.

    Please advise.
