As of 24 Jan 2018, vBulletin was upgraded to version 4.2.5, and, in conjunction with that, PHP was upgraded to version 7.
There were reported issues with vBulletin 4x when PHP 7 first appeared. At that time, vBulletin 4x was not compatible with PHP 7. It appears, based on reports being made here, that there are issues being experienced that are most probably due to continued incompatibility with PHP 7. So far, the reported issues are minor, in that they aren't breaking anything.
I'm checking into this. At worst, we may have to downgrade PHP.
I've created a sub-forum titled "KFN Access and Posting Problems" for collection of issues you are experiencing since the upgrade.
UPDATE (28 Jan 2018):
After successfully downgrading PHP to version 5.6, it appears that all the reported/observed issues we were having have been totally resoved. The KFN Access and Posting Problems sub-forum will remain however, as it's a good place to report any issues you may have accessing and/or posting here in KFN.
