XF 2.0 403 forbidden what is this

[turbos]

Hi, I'm having this issue. This is happening to very specific settings in the admin panel. I have tried rebuilding the files, clearing cache, changing browser, disabling settings, disabling addons... nothing.
The only plugins I'm using is audentio's UIX and the theme UIX2

I have contact the host and they told me this

seems an file right issue, it says it can't access the admin.php ; however when i try at this moment that seems to work, but maybe its looking in another directory or document root

.
and

there is nothing to fix from our side, this is a configuration issue of your site, not our server.
it says it can't find the admin.php in the location it is searching.

so I'm out of ideas, any tips ?

It's related to mod security - something your host should know about and will have to resolve.
