Sig Pro shows blank page instead of page. Example - www.luxury-magazine.ru/index.php?option=com_content&task=view&id=393&Itemid=91 (UPD - I had to downgrade to SIG free)

The problem is in Sig: everything is OK (except images), when it's switched off. When I've installed mambot, everything worked fine. But after a short period it stopped work correctly. I suppose, the reason is that PHP Safe Mode was swiched on. Administrator have switched off Safe Mode only for a short period to install mambot. Installation was impossible in Safe Mode.
How to correct this issue? Permanent disabling of Safe Mode is not allowed on my hosting.
Thanks!

Does anybody can help me?

Hi there!

When you receive the blank page, you receive also an server error message?

Can you please tell me what is written in the log file of the server for that time?

Thank you!

No, just absolutely empty page. Source of the page is also absolutely empty.

> Can you please tell me what is written in the log file of the server for that time?

Where I can find logs? File in logs directory in the root contains only infromation jf that kind - 64.1.215.163 - - [22/Jan/2009:02:03:27 +0300] "GET /index.php?option=com_content&task=blogsection&id=17&Itemid=123&limit=9&limitstart=9 HTTP/1.0" 200 32702 "-" "Mozilla/5.0 (Twiceler-0.9 www.cuil.com/twiceler/robot.html)" and so on.
Nothing like error messages.

After reinstall of SIG it begins to work fine. Very strange.
