Hi @mendesrocha,
If it’s a mod_security problem, then it should be logged somewhere – perhaps in the Apache error log, syslog, or a security audit log. This will depend on your server’s configuration. However, I’m fairly sure it’ll end up being an errant mod_security rule in the end, so you’re probably best off approaching your sysadmin.
