Oh, I see that here both bots were working: am.joomladev.de/info.php

This is the configuration, where the bots don't work: www.absolventen-merseburg.net/info.php

I've the same problem ... yesterday I've installed the new joomsef component including the mambot and my first page (content-page) was blank. Then I tried version 1.5 and the same happens. When I unpublish the bot everything works fine.

Also the bot JoomSeo causes a white page. What serverside specifications are recommended?

Greetings,
Dan
