Moodle lose some of the administrative privilege
You are playing with roles specially admin privilege or user privilege and you end up locking your self because of the wrong configuration. To restore it back to normal, you need to go to the database and find mdl_role_capabilities table and do a search for permission |= -1 and you will see the value of -1000. Just change the value to 1 for all the -1000.
