Chronoforms Ajax calls are treated as an exeption by Admin Tools (SQLiShield).
When I make a WAF exception to avoid this, this exception does not work.
In your documentation I read that I have to place the SEF plugin before the Admin Tools plugin. If I reorder this (Admin Tools plugin after SEF plugin) and then open the Components > Admin Tools configuration the Admin Tools plugin is placed before the SEF plugin again (in fact Admin Tools always becomes the first plugin all the time).
So I can't find a way to place the SEF plugin before the Admin Tools plugin. It seems that your software places it back at the first position all the time.
