Critical Error After Uploading backup website

  • Hi,
    I recently uploaded my WordPress site several months after it had been in use. After uploading the Sydney theme and Sydney Child theme, I’m seeing a “Critical Error” message on the front end, and I can’t access the dashboard to update plugins or themes. The error prevents me from doing anything, so I can’t check the WordPress or PHP version.

    Could outdated plugins or themes be causing this? Any advice on how to resolve this would be greatly appreciated!

  • Since the “Critical Error” appeared right after uploading the theme, it’s highly likely that the theme is the cause. The issue might stem from the theme’s incompatibility with the current WordPress or PHP version, especially if the theme is outdated. To confirm, temporarily deactivate the theme by renaming its folder via FTP or File Manager. If the site works with a default theme, the Sydney or Sydney Child theme is likely the issue.

    Also check your PHP version via the hosting panel and update it to 7.4 or 8.0 for better compatibility.

    For further help, contact your hosting provider to review error log.

    The reason for the error should be visible in the error log. You can find it in your hosting area. If necessary, the support of your hosting can help you.

    Alternatively, you could also enable debugging in WordPress. How to do this is described here: https://www.ads-software.com/support/article/debugging-in-wordpress/ – also here the support of your hosting can help you if necessary to edit the file accordingly.

    In both cases you should be able to see what the cause is in the logfile.

    Thanks, I will look into these things. For the time being I deactivated the suspicious plugins and themes to be able to log in.
