Publishing new pages gives “critical error”

  • I’m trying to publish a few new pages for an organization’s site but every time I go to publish them, it results in the “There has been a critical error on this website.” message. I’ve done some troubleshooting and I’m pretty sure it’s an issue with the custom theme, since reverting to a default theme fixes the problem. I’ve tried checking PHP version compatibility but the site is running PHP 7.4.3 and the compatibility checker only checks up to 7.3. I also tried raising PHP memory limit, increasing recursion and backtrack limits, and clearing the cache – no change.

    I turned on debugging and got a few notices but I’m not sure what to do with them, my experience with backend is limited and I don’t want to start fiddling with library files that could break the site. I’ll paste the messages below for reference. Any insight on what exactly is happening here, and any suggestions for fixes, are greatly appreciated.

    Your theme sirt seems to be the error.

    Access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/themes/ and rename or delete the directory of your currently active theme. That will force your site to use the default theme (Twenty Twenty-one, etc.).

    If that resolves the issue, next report the issue at that theme’s support forum.

    @t-p Thank you for your response. As noted in my original post, I’ve confirmed that the issue lies somewhere with the custom theme’s files. Per your suggestion I have attempted to follow up with the author of the theme, and will update this thread when I hear back from them.

    Is there no workaround for this in the meantime? Simply reverting to a default theme is not possible, as my organization is part of a larger network that needs the customization provided by our theme for stylistic consistency.
