Patron Pro 1.5.8 is out and it has various important fixes:
The “Already a member? Refresh…” label that needed to appear below the locked posts was missing. This label should now appear and change depending on the user or the patron accordingly.
Certain forms and settings were not saving when changing settings. These were fixed and those settings now should save correctly.
Some settings tabs were not working correctly. Now they should display and get selected correctly.
A potential vulnerability to x-site attacks and various PHP warnings were fixed.
This is an important update so you should update your plugin as soon as you can.
