I’ve set up a brand new latest version WordPress website ( uttoxeter.com ) and all worked well.
I could edit pages and posts and configure the site without issue.
I then downloaded and activated the Ultra Community Plugin.
I then noticed that I could no longer modify / configure the web site using the website Administrator account.
When I log in as Admin I get asked to log in again and when I do it says that I’ve successfully logged in but after approx 5 seconds I’m logged out again. If I do manage to get logged in I can seemingly make changes but when I hit ‘Publish’ I get a message : ‘You need a higher level of permission’ – ‘ Sorry you are not allowed to customize this site’.
Interestingly if I deactivate the Ultra Community Plugin then all is fine. I guess there is some conflict around the Administrator account.
Can anyone here advise me how to resolve this as it does seem to be an Ultra Community Plugin related issue.
