Existing wordpress site that's new to me.
When I enter the dashboard, the only options I have for administering plugins are the Edit view, where I can actually edit the code for any existing plugin. There is no Add New option, or the main Plugins index page. In fact, if I try to access ..../wp-admin/plugins.php by typing the url, I get a page that says "You do not have sufficient permissions to access this page." I need to add a new plug in, so I'm struggling to figure out how to get it back to "normal", or, how to manually activate/deactivate plugins. I do have some php skills, but have never done any custom wordpress development before, so just looking for a starting point.
I read that multi site feature can impact an admin users ability to modify plugins, etc, but this site is not using that feature. Also, I've read that custom themes can also impact the admin area. I know that this site is using a custom theme based on the Genesis framework. And that's as far as I've gotten in figuring this out.
Thanks in advance for any pointers in where to start looking to figure this out.
