[Mediawiki-l] Problem with Special:Statistics page

[Lasse Vogelsang]

Hi

I just installed mediawiki on a web server (hosted). It seems to work ok
except for the Special:Statistics page. It doesn't count the legitimate
content pages and the number of edits.

I got the following warnings when I configured the wiki:

Warning: set_time_limit(): Cannot set time limit in safe mode in
xxx/wiki/install-utils.inc on line 27 
# PHP 4.3.8: ok # Warning: PHP's register_globals option is enabled.
MediaWiki will work correctly, but this setting increases your exposure to
potential security vulnerabilities in PHP-based software running on your
server. You should disable it if you are able. 
# Warning: PHP's safe mode is active! You will likely have problems caused
by this. You may need to make the 'images' subdirectory writable or specify
a TMP environment variable pointing to a writable temporary directory owned
by you, since safe mode breaks the system temporary directory. 
# PHP server API is apache; ok, using pretty URLs (index.php/Page_Title) 
# Have XML / Latin1-UTF-8 conversion support. 
# PHP's memory_limit is 8M. If this is too low, installation may fail!
Attempting to raise limit to 20M... failed. 
# Have zlib support; enabling output compression. 
# Found GD graphics library built-in, image thumbnailing will be enabled if
you enable uploads. 

Anything I can do?

Are there any other critical problems I could encounter with these warnings?
I know about the image upload problem.

Thanks in advance
