vbulletin 3.6.4 / 3.6.5 rare fatal errors viewing threads w xcache 1.0.3

Vbulletin 3.6.4 (security patched)
php 4.4.5
xcache 1.0.3 (compiled from source -- you are missing this version in your ticket dropdowns)

Overall xcache is running excellent. However, I have had sporadic reports of users getting the following error when clicking a thread after using "new posts." I have also seen reports of this at

Fatal error: Direct instantiation of vB_Postbit class prohibited. Use the vB_Postbit_Factory class. in /includes/class_postbit.php on line 239

Here is a link of other reports of this error at

I also noticed when upgrading from vb 3.5.3 to 3.6.5 on another forum that there were some problems during the upgrade that never happened before xcache. May be unrelated. I had to disable xcache for moodle on one site (I'll make another ticket for that).

  • Milestone set to 1.2.1
  • Version set to 1.2-dev

Please DO NOT use 1.0.3 as it is deprecated !! however I can reproduce your problem with 1.2-dev too with php 4.4.6.

Replying to judas_iscariote:

Thank you for confirming and replicating.

Your reply confuses me. The Download page itself says 1.0.3 is the version to get for php4 for "stability." Is this no longer true? And if that is a release version, why is there no dropdown/option for 1.0.3 in the ticket system? Does 1.2 fix anything wrong with 1.0.3 or is it about performance enhancements? How much performance will I lose if I turn off "optimizer" to see if that is causing problems -- or is that not really doing anything (hard to find these details here).

i'm tracking down the vB_Postbit problem, but moodle problem should have been fixed, in 1.2.0 IIRC
