MySQL 5.5 upgrade ‘broke’ WordPress [closed]

Your best bet would be to take DB and site backup and see if you can get it working on local server or any other server, if you do get it running the problem is with the way server probably changed some settings while upgrading.

Also in the screenshot image isn’t loaded, but can you open developer tools in your favorite browser and see what path is it looking to get the image and can you access it just by going to that url?
Btw if you can’t access that image by entering it’s path, perhaps check who owns them files.. i’m guessing owner and group should be www-data:www-data

Thanks
