XML warning problem


I tried to find my problem in the forum but couldn’t find it.
I installed Event Calendar / Scheduler in a Wordpress 2.9.2 site.
I get a warning:
Warning: SimpleXMLElement::asXML(/home/pol3376/amsterdambbvondelpark.com/www/cms/wp-content/plugins/event-calendar-scheduler/com_scheduler_log.xml) [simplexmlelement.asxml]: failed to open stream: Permission denied in /home/pol3376/amsterdambbvondelpark.com/www/cms/wp-content/plugins/event-calendar-scheduler/codebase/dhtmlxSchedulerConfigurator.php on line 317
on this website: amsterdambbvondelpark.com/cm … mode=month

I am running php 5 so that’s not the problem
Also I am using plugin qtranslate.

What can I do?

Thanx in advance, Ariane

Do you have “debug mode” enabled.
In case of debug mode, script attempts to write log file, and if plugin’s folder has not write permission - script will throw an error similar to above one.

‘debug mode’ was not enabled.
After a reset of the rights of the documents suddenly the error disappeared and everything is working fine now.

Thanks, Ariane
