I have the same problem as AdrialHY with my site.
After I login through http://perichoresis.me/wp-admin, insert username & password, I will straight away go to "profile". There are only 2 buttons on the left side of my dashboard 1. Dashboard 2. Profile. If I click on the "dashboard" button, I will only see WordPress Blog & Other WordPress News. When I click on the "Screen option" button, there's only 2 options under the show on screen: wordpress blog & other wordpress news.
I have checked my phpMyAdmin as suggested by govpatel.
You need to go in phpmyadmin and click on your database
look for wp_users and click on browse 1st icon
you will see list of user if you have more then one
check if your ID is one
if is one then click on wp_usermeta
and check if you have this in table 14 wp_capabilities
I have two user logins because I have two sites. The site I am trying to resolve is user ID 2.
When I click on wp_usermeta and look at row 14 it reads as above, i.e.
But, as I said, the ID is 2 for the user_login on this site.
