1. When I click on Edit next to the user name on the top right side of the header I get a 500 error message. This is the link that gives me the 500 error: http://localhost:8888/testsite/administrator/index.php?option=com_admin&view=profiles
2. I get an "Edit not permitted" message on some sections like article manager, extension manager, etc. But only the first time I go there. If I navigate away from those pages and come back to them the message doesn't appear, until the next session.
