Error while posting new thread (upgrade 3.5.4 to 3.7.2)

[flup]

My members seem to have a problem while posting a new thread, I don't have this problem myself.. anyone knows the source?

Translation of the error:
The website .... cannot be opened
The transaction(? not sure ?) has been canceled.

It seems to be apearing since my upgrade from 3.5.2 to 3.7.4 (which showed no errors what so ever, even all modifications (besides split-forum home and vbiproarcade and vbshout, but they have no hooks in newthread as far as I know) have been removed before upgrading.

Also my WYSIWYG editor shows some mallfunction with styling after the upgrade, perhaps anyone else had this problem?

Thanks!

The only way to trouble shoot this is to create a default style, and disable plugins and try to recreate the error.

I have these hooks in newthread locations:

vBSEO New Thread: Controls (newthread_form_complete)
Cyb - Auto Reply - PR (newthread_post_complete)

Anyone? Kinda annoying that no user can post on my forums right now..

Guess it has something to do with the modifications to SHOWTHREAD template (is that even possible?) I changed some things for the CSFR Protection in custom templates (as they differ from v3.5.4 to v.3.7.2), but I noticed there where a lot more changes made in that template during the upgrades than only those.

I reverted them now and at least some other problems are fixed.

Nopes, that wasn't the problem unfortunatly..

Did you try what FRDS suggested?

Create a new style with no parent - Styles & Templates > Style Manager > Add New Style > no parent - then browse the site using that totally default vbulletin style - do you still have the same problem?

Totally Default still gave me errors, then I started to disable all products.. seems that this (https://vborg.vbsupport.ru/showthread.php?t=184571) modification caused the errors, however I still don't know why and were the error occured.. to bad, cause I liked the modification alot!

Read the thread. Maybe this issue has been brought up by other users and there may be a fix posted in the thread.

Yep, already doing that,.. it's just.. 33 pages long!! :P
