I had to use a backup, because i wanted to take a step back.
Now the site gives a critical error. When i deactivate the toolset-blocks plugin, the error disappears.
Here are the error messages:
Uncaught ReflectionException: Class "OTGS\Toolset\Views\Controller\Cache\Meta\Post" does not exist in...... wp-content/plugins/cred-frontend-editor/vendor/toolset/toolset-common/lib/auryn/lib/StandardReflector.php:29
and:
Next OTGS\Toolset\Common\Auryn\InjectionException: Could not make \OTGS\Toolset\Views\Controller\Cache: Class "OTGS\Toolset\Views\Controller\Cache\Meta\Post" does not exist in ....public_html/wp-content/plugins/cred-frontend-editor/vendor/toolset/toolset-common/lib/auryn/lib/Injector.php:422 Stack trace: #0
and a huge list more. It seems to be something cache related?
If you want me to post all error messages, please make the next post private.
Did your backup include restoring older plugin versions?
I would double check that you have the latest versions of Toolset plugins installed, which you can double-check from the manual download section of your account download page: https://toolset.com/account/downloads/
The kind of errors you shared can result from mixing plugin versions of individual components from different versions.
If you update all Toolset plugins to the current versions I expect you should no longer see such errors.
No it's a backup from only 12 hours ago. Nothing has changed. I checked and all the latest plugins are installed. I also tried to disable all other plugins, but the problem kept occurring when i activated the toolset blocks plugin.
Luckily i had a staging version as well, when i pushed that to live, it worked.
