bbcode problem

[Delphiprogrammi]

hi folks,

I have a serious problem involving bbcode parsing.I have a custom bugtracking script i used with success for several monts.When vBulletin released the two most recent updates in response to discovered XSS security holes.The bbcode parsing function stopped to work.In my posts i always see raw (unparsed) bbcode.I reported this to the custom script developer and he checked and said bbcode parsing whas working fine and i believe him on his word.What makes the whole case even more strange is that build in bbcode you can see at www.yourboard.com/forums/misc.php?do=bbcode is failing to.I'm digging for weeks after this.I double and double checked my settings there is nothing wrong with them.So my last hope is that anybody in here has any idea what might the cause of this the problem.I can't provide any code the script is encoded (ioncube)I tryed to rebuild my options cache and postcache nope no solution.He or She who's able to solve this can have a can of beer .I can't ask over at vbulletin.com because it's a custom modification but bbcode did work fine until those two updates.BBcode does work fine outside of the bugtracking script
