Web server software (WebServerX) is not supported. Sorry
This is one of the errors that server administrators would usually come across after installing Moodle
The reason why the server generates this is due to the mod_security configuration.
SOLUTION
In order to resolve the issue, one must edit the following file:
# vi /usr/local/apache/conf/modsec2.conf
and comment on the line:
SecServerSignature "WebServerX"
i.e.
#SecServerSignature "WebServerX"
Save these changes and Restart Apache Services
This should resolve the issue and Moodle would start working fine.
