This plugin looks wonderful. However, after initially setting it up, for some reason I'm not able to access any of the groupings of settings other than the "Custom Field Template Options" section. In other words, I can't toggle open the "Global Settings", "ADMIN CSS", etc. In fact, although the top-most "Custom Fields Options" section is open, I can't toggle it closed. All toggles/dropdowns outside of this plugin seem to working fine.
Any ideas on what could be causing this? Much thanks in advance for any help!
