Solved [Resolved] Posts on forum disappear!

Hello,

we had the same problem of empty posts in some cases where links are included. We found the post of Ardenlyn here and the "shorten url" feature caused our problem too. Crazy, but the same site copied to my local xampp or a second local machine with lampp worked fine. :huh:

I have analysed this on our live server (FreeBSD) and I found the preg_replace() inside KunenaBBCodeInterpreter::PostProcessing() runs in a PREG_BACKTRACK_LIMIT_ERROR (get by preg_last_error()). So my first idea was to assign the replace result to a local variable and check last error before replacing original text.
But additionally I found the cause of the error: it's the "\3?" inside the search pattern. I have replaced this by "(http(s?)/\/)?" which doesn't change the meaning but makes preg_replace() happy.

We are using Joomla! 1.7.3 and Kunena 1.7.1, xampp has PHP 5.3.1 but lampp and our live server have running PHP 5.3.8.

Another little thing inside the same file:
In 1.7.1 you (the developers) have added "index.php" two times to a regular expression. Because you mean the concrete character "." you should escape it. Actually e.g. "index4php" would match too.
(sorry, if this is the wrong place to tell such things)

Best regards,
Hoffi

This fixed it for me too! Thanks!

What?

If you switch off the "shorten url" feature in the Kunena-backend posts will no longer disappear.

Incorrect.

Hi. I saw today strange problem. All posts with added link are showing nothing. When I try to edit text is displaying normaly and after save the same problem. Not showing post.
When i remove linka all it's ok.


Kunena 1.7.2, Joomla 1.5.25.

I had the same problems on our forums.

Switched the "Trim long URLs" to NO.

And my missing forum posts reappeared.

ew128: The answer is here, in this topic.

(1) If you want Kunena to work, disable Legacy mode
(2) If you want Kunena to work, upgrade to K 1.7.2
(3) If you want Kunena Latest to work, upgrade to Kunena Latest 1.7.2
(4) If you want Kunena to work with Community Builder, upgrade to CB 1.7.1
(5) If you want Kunena to work with uddeIM, upgrade to uddeIM 2.6
(6) If you want Kunena to work properly, use a Kunena template that was designed for K 1.7; if you have problems with K 1.7.2 while you are using the EVOLUTION SLATE - FREE Kunena 1.6 then please direct your questions to the author of that template. We do not support or endorse that template with K 1.7.2.
