Hello,
1.I don't think the memory limit is the cause. The limit is 32M. I think it should be enough. Anyway, I've spoken to my hoster, he won't increase the memory limit...
Otherwise I followed the process from your links.
From the debug, here is what I get:
[code:1]Notice: Undefined index: 0 in /home/emar7562/public_html/passionducinema.com/components/com_sh404sef/sef_ext/com_adsmanager.php on line 61
Notice: Trying to get property of non-object in /home/emar7562/public_html/passionducinema.com/components/com_sh404sef/sef_ext/com_adsmanager.php on line 61[/code:1]
The problem doesn't comes from the adsmanager tab, because when I disable it, the page remains blank.
When I check the error logs, I see the following:
[code:1][Fri Apr 24 14:51:38 2009] [error] [client 85.102.190.205] File does not exist: /home/emar7562/public_html/passionducinema.com/404.shtml, referer:

[/code:1]
But I dont understant the directory "xc3\xa9"... it's weird.
2. I checked the live_site field in the configuration.php file. It is empty. So the problem should come from something else.
