Solved [Resolved] Posts on forum disappear!

I set everything back to the default settings. No joy.

So if I could get you access to the frontend of the forum, would that be enough? Or would you need admin?

Let me see if I understand the specifics of this problem and, BTW, the HTML that you posted 5 messages ago did not help me in the least in understanding the problem. I mean, I pasted the HTML into a browser and said to myself, "so what?" Without a context, this code snippet is meaningless.

You say that under certain circumstances (but we're not entirely sure - from reading the first message in this topic - exactly what those circumstances are) messages seem to "disappear". Can I correctly infer from what you have written that messages posted to the forum are simply not there at all? In other words, the messages are not even being stored on the database? Or do you mean something else. Bear with me on this: I'm simply going on words used in the subject of this topic.

It would help to understand the context under which these messages mysteriously disappear. If I could see your website (as a user would see your website) this may assist matters.

I assume that you have carefully looked at the Kunena installation guide and followed the recommendations made in that article. Of course you have, so I'm also assuming that you've established to your own satisfaction that you've got a test website and that Kunena works perfectly well on that test website? Right?

I see that you have some odd settings for your Kunena menu so I assume that you've decided to go your own way as far as setting up the Kunena menu and its related links? No? Maybe you should read the FAQs page and look at the section How do I restore my Kunena menu?

I also see from your configuration settings that you have disallowed image uploads. Maybe this setting changed when you reverted to the default configuration settings. It might help if I could see your updated configuration settings, please.

So, in summary, we have a situation where messages are "disappearing" or not appearing under certain circumstances - seems to happen when you try to upload an image or add an image or post the URL of an image or something along those lines - but we're not entirely sure what kinds of images these are (i.e. are they .JPG or are they .JPEG). And all the "usual" lines of troubleshooting seem to have been exhausted. Would that about correctly summarise the situation?

Sorry to seem a little pedantic about the details but I just want to make sure that I've covered all the bases.

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
