Price Packages not editable (again)

I’m experiencing the same problem I had back in January. Here’s the original post: https://wpgeodirectory.com/support/topic/price-packages-not-editable/

The initial problem was fixed by updating the Payment Manager plugin, however the problem has returned and was not fixed by updating to the latest version (all GD plugging were dated last night, error persists).

I’m not sure when the problem started re-occuring as I only recently turned my development attention back to adjusting/adding paid options a few days ago (site not yet live).

The problem is exactly the same (I can not edit or add Prices), except that I am not getting any error messages this time.

The site URL and login info is the same as in the original post thread copied above.
