Hi
I had installed and configured two vbulletin 4.2.5 forums both of which worked perfectly on a webhosting

Now they both give this error, what happened? they both give the same error

I know that this reply came a little bit too late, but this error is due to an incompatible PHP version configured on your server.

For that version of vBulletin, you need to install and configure PHP 5.6
