Fatal Error after upgrading to IPS 5

[agent781]

Upgraded IPS, front end looks to be OK. But in the admin panel I'm getting this error when I log into the admin panel. Any help would be appreciated!

Fatal error: Type of IPS\core\extensions\core\Statistics\_Conversations::$controller must be ?string (as in class IPS\core\Statistics\Chart) in /home/.com/public_html/forum/applications/core/extensions/core/Statistics/Conversations.php on line 23

And line 23 is:

class _Conversations extends \IPS\core\Statistics\Chart

From which version did you upgrade?

4.7.21. I redownloaded the files, extracted them and re-uploaded and that fixed it. Must have been a bad file.
