Maximum Capacity of Meta Fields?

Hello,

i’m not optimistic to get an answer, but i’m trying anyway. I have discovered that this plugin is the only one that works together properly with the plugin Adminimize. So i was happy to have found a solution. Now i discovered that not all meta fields appear in the settings area (“What fields may be exported?”). I’m working with a huge amount of fields (> 200; some already deleted fields appear), so i’m wondering if i have exceeded a certain maximum capacity? If anyone has an explanation, i’d be grateful! Thank you.

Regards, Harald
