Thread:Project:Support desk/Some pages truncated to last 4,435 bytes

I have installed MediaWiki on my linux platform, hosted by streamline.net. The wiki works okay, but when some pages are viewed (Community_Portal, User:, etc.), they are truncated to their last 4,435 bytes. I have checked in multiple browsers, increased the php memory limit to 64M and turned on php errors, all to no avail.

Can anyone assist?

MediaWiki v1.17.0 PHP v5.2.6 (cgi-fcgi) MySQL v5.0.77-log

My wiki URL is http://help.lexpos.com
