_Vault_ Posted April 5, 2022 Share Posted April 5, 2022 My site is down after upgrading to 4.6.12. Upgrade went smooth, no issues reported but now the site is completely down. I found this error in the php log: [05-Apr-2022 19:17:49 UTC] PHP Fatal error: Cannot use "parent" when current class scope has no parent in /srv/http/root/html/system/Theme/Theme.php(2632) : eval()'d code on line 37 Link to comment Share on other sites More sharing options...

One of them isn't updated to PHP 8 yet. Link to comment Share on other sites More sharing options...
Jim M Posted April 5, 2022 Share Posted April 5, 2022 Please try recovery mode as Adriano suggested and let us know if that helps. Link to comment Share on other sites More sharing options...
_Vault_ Posted April 5, 2022 Author Share Posted April 5, 2022 (edited) Thanks! When I activate Recovery Mode, the site loads, but it's preventing ACP Access: 1S107/3 Before you are able to use the Admin Control Panel, you must edit 'constants.php' and remove the following line: define( 'RECOVERY_MODE', TRUE ); But I have to go to ACP to put the site "Offline" and disable the plugins one by one or? - Edit: Forget it, after removing the line I can now acces the ACP again. I'll now check whats going on. Cheers! Edited April 5, 2022 by _Vault_ Link to comment Share on other sites More sharing options...
Jim M Posted April 5, 2022 Share Posted April 5, 2022 You will want to hit the ACP at the root, on the default software this would be /admin but you will need to go directly to your admin's modified folder name. Often you will get this error if you try and use an existing session or go to a different page. If you're still having issues, please update the access details in the Client Area and we can take a look. Link to comment Share on other sites More sharing options...
Solution _Vault_ Posted April 5, 2022 Author Solution Share Posted April 5, 2022 (edited) Thank you both @Jim M and @Adriano Faria for the tip with the recovery mode and how to use it. The plugin causing the error was:Back To Top 1.0.5 By Pete Treanor http://invisionfocus.com After enabling the plugins one by one, and clearing the cache after each one, I was able to identify it. Luckily it's one that I can easily spare. Thanks again! 🙂 Edited April 5, 2022 by _Vault_ Jim M and Adriano Faria 2 Link to comment Share on other sites More sharing options...
