Logged out, visiting my site as an unregistered user–
When Memberships tries to redirect me to any Membership specific page (Protected Content, Login etc) it times out and returns with the following
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at firstname.lastname@example.org to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Additionally, a 302 Found error was encountered while trying to use an ErrorDocument to handle the request.
I have deactivated Memberships & reactivated, but the same result occurred. When logged in, the dashboard works as normal, and all pages function as they should.
Sidenote: I was not revising any code in the backend when this began occurring, other than the child theme style.css. Also, I have not revised any files within the Memberships plugin itself.
