It could be mod_security. http://wiki.modxcms.com/index.php/What_is_mod_security_and_how_does_it_affect_me

See if there is anything in the MODX error log (Reports -> Error log).

I had already looked that link but nothing, and the error log is blank.
I reinstalled everything, installed new versions 201rc3 and 210rc4 But nothing.

Idon’t know.

Thank’ for all Bob and for your guide.
