Re: Calendar?
pidan, blank screens mean (usually) too little memory_limit in php.ini issues in your server. You need at least 16 Mb in there. Search the http://doc.tikiwiki.org/faq6 and Documentation if needed for more help.
And there was a bug in jscalendar that modified the time when you edit a calendar item, but without jscalendar feature worked for me. And some coders reported to have fixed jscalendar in 1.9.8 code...
