I installed it on Thursday, activate it, do the basics ... So far so good.
Later ... at night, I installed "capability-manager-enhanced", I made some adjustments, working again with "All-in-One Event Calendar" and ... well, out of nowhere, I run out privileges.
I assumed that my problem was caused by "capability-manager-enhanced" ... I did everything humanly possible to fix it ... I could not!
On Saturday I restored my backup (two weeks earlier) Database and other WordPress, reinstalled Sunday "All-in-One Event Calendar" reset all pages and posts lost and went to sleep.
Today Monday, starting at 08:00 PM, I started working with "All-in-One Event Calendar" and suddenly, without saying "water goes," I run my admin access.
I just solved by following some of the tips I found in "http://wp-relief.com/2011/12/01/user-roles-in-the-wordpress-database/" (All my WordPress user roles are gone , how do I fix it!) and then began to clear and try everything that was necessary to "wp_user_roles" in the wp_options table, until I regained control of administrator and disable plugin "" all-in-One Event Calendar ".
Too bad "All-in-One Event Calendar" painted for good, will be another opportunity.
EYE 1: Before you read this and tried all possible solutions that support delivery of "All-in-One Event Calendar" and nothing worked.
EYE 2: Excuse my English is not my native language.
