You don't have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
This is likely not to be a b2evolution issue but a hosting one relating to ModSecurity
Try disabling ModSecurity via cpanel for example, temporarily, then ask your host to white list the issue. I have had this numerous times since moving host. Some people disable ModSecurity permanently
