XF 2.2 Upgrade Problems

[vtcnc]

Admin upgraded and we are not sure what is going on with these errors. Can someone explain this?

This can happen when running PHP <7.4 with debug mode enabled. It has already been fixed for the next version, but in the meantime you would need to either upgrade to PHP 7.4+ or disable debug mode. We recommend against running production sites in debug mode anyway.
