I can’t figure this out but I recently tried to add a post to  
something and kept getting this error:

Precondition Failed  
The precondition on the request for the URL /admin/pages/edit/16  
evaluated to false.

Which Ive never seen before + traced it back to the fact that its  
caused using something like this in your template:

echo x

This is without using a filter.

Any ideas? (I searched ml archives and only saw a few parsing  
bugs). Using 0.5.2.

Thanks.

People typically get a “precondition failed” error when their Web host  
is running mod\_security and they post one of the words that are on the  
mod\_security black list. You can check with your Web host to see if  
there is a way to work around this.
