Moved: How can fix Fatal error

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.

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 advanced users.

Here’s a video screencast:

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

That should resolve the issue, if not 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.

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.
