Hi Everyone,

Iam encountering a Black colour full screen issue when trying to access the Concrete CMS dashboard. After logging in, the screen turns black, and none of the options load.

Iam using Concrete CMS version 9.2.1 on PHP 8.1, and this issue started recently after a theme update. I have tried clearing the cache and checking for errors in the logs, but I haven’t found a solution yet.

Has anyone else experienced this [“BLACK SCREEN”](https://blackscreen.onl/) issue? Any suggestions on how to resolve it would be greatly appreciated.

Thanks in advance!

Check your browser console for errors especially javascript errors.  
And clear your browser cache.

Managed to “fix” it by using Edge instead of Firefox.  
Was able to see the upgrade messages / notifications and ok them.

@romromillys I think I have seen this issue before and it turned out to be a css conflict with the theme’s bootstrap.css file and the upgrade message css declaration.  
If you temporarily rename the theme bootstrap.css file to bootstrapold.css, that should allow you to see the upgrade message and dismiss it, you can then restore your bootstrap file and all should be good.
