I have a wordpress installation on my website https://advisorjoint.com/blogs. Now the issue that I am facing is that all users except admin are getting "You do not have sufficient permissions to access this page." error when they try to access their wordpress dashboard.
One thing is that when they try to access dashboard from http://advisorjoint.com/blogs/wp-admin/ then they will get this error, however when they change the URL to their Blog_URL/wp-admin then they are able to access the wordpress dashboard. Also when they try to access someone else's blog dashboard, they get an error that they are trying to access someone else's blog. Below which it shows your sites and their sites are displayed. However in your sites the main blog URL is also there.
I think there is some user role issue with my blog and I have tried to change the wp_user_roles in wp_option table, to the default user value, still I am facing the same issue.
I used a plugin named "Multisite User Management" which might have caused this problem.
Any help will be greatly appreciated.
