Override apache version
Some servers may use nginx apache, or may not have apache version available. MenaPro uses htaccess to prevent direct access to some files. The rules needed for this are different in Apache 2.2 and 2.4. MenaPro will try to detect your apache version, but if can not you can tell what it is.
In ftp navigate to menacorexxxx->backend->config->params and uncomment the line "apache_version". Remember to add a comma on the line before. Then go back to your backend->config->security->repair.
