Probably it's mod_security or other IPS triggering against sql injection pattern.

Well, it depends ...
You must do multiple tests and determine, what's causing IPS triggering.
Try various sql queries. For example, try to go without "limit x,y":

and (select 1 from user limit 0,1)=1

Instead:

and (select 1 from user where id>1)=1

and (select 1 from user where id=1)=1

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Probably it's triggering on subselects. Try inline sql comments:

Code:

and/**/(/**/select/**/1/**/from/**/user/**/where/**/id>1)/**/=/**/1

sorry for the bump, but I'm pretty sure the word user is making the problem.
