Upgrade to at least 4.2.3, better still, 4.2.4.

You are running a newer version of php (5.5 +) which isnt compatible with older vB versions.

I would consider that "fix" to be a band-aid until you can upgrade your vB to a version compatible with your PHP as Paul suggested.

You have not fixed anything, you are simply hiding the errors, some things will break on 5.5, you cannot hide them.

There are instructions in the manual on how to do an upgrade - https://www.vbulletin.com/docs/html/upgrade .

Make sure you do a database backup prior to upgrading.
