Important Category Index CSS suddenly not loading in production site - Help please

Hi:

I had a site using kunena from the last months without any problem. Some days ago, suddenly stops loading the css from the category index. When i enter a topic, the css works, but not the index (so the users get a nasty entrance). This is the link to the category index:

www.fender.cl/index.php?option=com_kunen...c=listcat&Itemid=139

I searched trough the forums and I noticed that several people talks about a configuration option in frontend called: use joomla style? (yes/no). I searched trough all the configuration options and I cannot find it.

I am using joomla 1.5 last revision and the last revision of kunena. I will be very grateful if someone can help me, because I really don´t kno what to do, and my users are mailing me with compliments. Thanks in advance

This is the configuration report from kunena control panel:

Hello,

This doc will help you : docs.kunena.org/index.php/How_to_diagnose_blank_page_on_kunena

Use Joomla Style = Yes/No is a feature of the Blue Eagle (default) template. It is not a feature of the user-written template that you are using.

You might also find the guide Search Engine Optimisation (SEO) useful to you, too.

Solved:

The problem was with memory allocation. Maybe the multiple plugins (k2, jomsocial) exhausted the memory allocation. I used the debug option (thanks to the xillibit recomendation) and I noticed the allocation memory error. I searched the web and I found this roundaround in joomla

forum.joomla.org/viewtopic.php?p=1381532

Thanks for the help and suggestions.

Andres
