I did some screen prints and here is my CB Plugin page. I'm keeping things simple and minimal first.
I have five "test" registered users (not subscribed). I tried to login one of these and I get the error message "Warning A Membership is needed for access". This act also disables the user. Each one I've tried that received the warning message caused the user to be disabled.(?)
I disabled the CBSubs Plugin. Another "test" registered user is logged in. It accepts the login. If I access the calendar from the "Calendar Events" it is opened but with no events showing. If I try to access from Latest Events I get the error message "You are not authorised to create/edit events".
I enabled the CBSubs Plugin. Tried the subscribed registered user. Same thing happens as above.Access to calendar with no events and access from Latest Events gets the error message "You are not authorised ..."
I've changed the access on these plugins from public to registered with no change in error messages.
What else should I check??
