Problem with [html][/html]

For some reason, when I try to post this using the following code inside  as an admin, I get a blank screen after the topic has been created:

[html]<div id="news-text"><p>Hydra are members of a family of radially symmetric animals (Cnidaria), all of which use specialized cnidocytes to catch prey. This family also includes well-known creatures such as jellyfish and corals, which, like other cnidarians, have the simple design of a mouth surrounded by tentacles. Hydra tentacles contain barbed, poison containing cnidocytes that they use to stun animals like the <a href="http://biology-forums.com/definitions/index.php?title=Special%3ASearch&redirs=0&search=water+flea/" rel="tag" class="textTag">water flea</a>, <a href="http://biology-forums.com/definitions/index.php?title=Special%3ASearch&redirs=0&search=daphnia/" rel="tag" class="textTag">Daphnia</a>, before eating them alive, and to protect themselves from attack by other animals.</p><br /><p>Researchers from the University of California lead by Dr David Plachetzki have discovered that the light sensitive protein opsin found in sensory cells is able to regulate the firing of harpoon-like cnidocytes. These light <a href="http://biology-forums.com/definitions/index.php?title=Special%3ASearch&redirs=0&search=sensitive+neurons/" rel="tag" class="textTag">sensitive neurons</a> are found integrated into arsenals that include the stinging cnidocytes as well as desmoneme cnidocytes, used to grasp prey, and sticky isorhiza, which help the hydra to summersault at 10cm a day.</p><br /><p>

</p><br /><p class="desc clear-left">This is the fresh water polyp, <em>Hydra magnipapillata</em>. Credit: Dr. David Plachetzki, University of California</p><br />The linking of opsin to cnidocytes explains how hydra are able to respond to light even though they do not have eyes. Dr Plachetzki described how other proteins necessary for phototransduction are also present in the <a href="http://biology-forums.com/definitions/index.php?title=Special%3ASearch&redirs=0&search=sensory+cells/" rel="tag" class="textTag">sensory cells</a>. "Not only did we find opsin in the <a href="http://biology-forums.com/definitions/index.php?title=Special%3ASearch&redirs=0&search=sensory+neurons/" rel="tag" class="textTag">sensory neurons</a> that connect to cnidocytes in the hydra, but we also found other components of phototransduction in these cells. These included cyclic nucleotide gated ion channels (CNG) required to transfer the signal and a hydra version of arrestin, which wipes the phototransduction slate clean for a second signal."<br /><p>Dr Plachetzki continued, "We were also able to demonstrate that cnidocyte firing itself is effected by the light environment and that these effects are reversed when components of the phototransduction cascade are turned off."</p><br /><p>Cnidarians have been around for over 600 million years. However the hydra's simple approach to using light, to aid survival and increase their chances of catching prey, uses the same visual pathway as humans and hints at a common ancestor.<br/></p><br /><p><strong>More information:</strong> Cnidocyte discharge is regulated by light and opsin-mediated phototransduction, David C Plachetzki, Caitlin R Fong and Todd H Oakley, <em>BMC Biology</em> (in press)<br/></p><br /><p>Provided by BioMed Central (<a href="http://www.physorg.com/partners/biomed-central/" rel="news">news</a> : <a href="http://www.biomedcentral.com/" target="_blank">web</a>)</p><br /></div><img src="" border="0" height="1" width="1" />[/html]

Admins, try placing creating a topic on your forum with the exact same code as above.

Strangely, when I remove this part from the code: <a href="http://cdn.physorg.com/newman/gfx/news/hires/2012/1-seeingwithou.jpg">Enlarge</a>

It works normally. Could someone tell me if this is an SMF bug?

[Illori]

does your server have mod_security enabled? if so try to get it disabled and check again.

[OnzeDanny]

I have tried it into my forum.
Copied your complete code and it works ...
See attachment 

[Shambles]

Works good on my forum too, though had we still been in mod_security and behind a WAF, the phrase "Hydra are members of a family" would almost certainly have white-screened me (as we always had problems with words like "update", "select", "member" etc.)

Try resubmitting with the word "member" disguised as "m[b][/b]ember" which may help determine if (as Illori says) you're upsetting the mod_security of your host (if fitted)

[Biology Forums]

I disabled it using htaccess using this code (#vi .htaccess


<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off

)

and it still didn't work: Here's another one, please try it and tell me if it's working!

Can someone please help me with this?

Who should I report this bug to, here's another page that's doing the same thing.

[Aleksi "Lex" Kilpinen]

Please, see if your server error logs have any PHP errors or warnings that might be related. Errors concerning memory, execution time, output etc.
My first guess would be that your system has a bottleneck somewhere causing this.

There is nothing wrong with the code you used (see attachment).

Like: Aleksi "Lex" Kilpinen said, see or you can find errors in your log files (even in the SMF admin error log ...)

[Biology Forums]

That's not far! I want it to work with me too, what the heck.

[Aleksi "Lex" Kilpinen]

Did you check the logs?

Did you check the logs?

I have so many errors that I turned that feature off. If I turn it on, I will get 1000000 errors in two seconds.

[Aleksi "Lex" Kilpinen]

Well, that tells us something - but really, turning off the logs does not help, it hides problems instead of fixing them.

I was quite serious. The logs are there for a reason, and if you want us to be able to help you, then you should help us help you by doing what we ask you to do.
I asked you to check your server's error logs, as that is the place anyone should first see when something is not working right on the server side.

After taking hours to clear up my errors, I've discovered that this doesn't cause any errors No errors showed up when I created the topic.

does your server have mod_security enabled? if so try to get it disabled and check again.
