After updating my Concrete CMS site to the latest version, my website and admin panel are only showing a black screen. I can’t access anything, and clearing the cache didn’t help.
I have tried:
Checking error logs but didn’t find anything obvious.
Disabling custom themes and add-ons via FTP.
Ensuring my PHP version meets the latest requirements.
Has anyone else faced this issue? Could this be related to a database error, file permission issue, or missing dependencies? Any help would be greatly appreciated!
I have seen something like this before and it was a css conflict between the welcome overlay and the themes bootstrap.css file.
The ‘Hack’ to get past the welcome overlay was to rename the bootstrap.css file to bootstrapold.css.
This then allowed the overlay to be cleared and since it was a ‘run-once’ file, I was able to rename the bootstrapold.css back to bootstrap.css and all was good from then on.
