====== Error 403 or 406 on certain page content ======

:!: This is usually a problem caused by overly-restrictive security policies set in the webserver (Usually [[http://www.modsecurity.org|mod_security]]).

There is no way to fix this in DokuWiki because it is not a DokuWiki caused problem. You need to check your webserver audit logs to identify the problematic rule and disable it.

Commonly problematic words are parts of SQL statements or mail commands like 

  * select ... from
  * drop ...
  * to: ...
