I upgraded (via webadmin) my NC install from 11 to 12(latest)
After upgrade I get the following message in admin view:
Some files have not passed the integrity check.
Details are showing:
- Certificate is not valid.
[calendar] => Array
[EXCEPTION] => Array
[class] => OC\IntegrityCheck\Exceptions\InvalidSignatureException
[message] => Certificate is not valid.
Any idea on how to fix this?
