recently we're started to have "You do not have sufficient permissions to access this page" error in wp_die() screen when trying to upgrade our Payment History of Module Pages, as EDD promting us in the dashboard.
Earlier, this upgrade operations work flawlessly. Of course, the upgrade operations are tried to start using the admin account.
Codex says that such situation can occure when add submenu page() is hooked onto a hook different from "admin_menu". But EDD is hooking right onto admin menu.
WP is 3.5, EDD is 188.8.131.52, php is 5.3.*
Thnx in advance.
