403 Error when saving settings in WP-members

For others, thought this might help.
After trying various times to save settings in WP-members, I got a 403 Forbidden error each time when clicking the save button.

This is what I did to resolve:
In cPanel navigate to the Security Menu and enter ModSecurity module.
Disable it for your site. Log out of your wordpress admin site and back in… Voila!

Worked for me, hope it works for others.

Please note, I have another security plugin, so this might not be an applicable fix for everyone.
