Possibly conflicting plugin: s2Member 3.1
It overrides two WordPress General Settings:
-Anyone Can Register = [0]
-Default Role = [a proprietary membership level]
I already tried deactivating/uninstalling s2Member and changing the aforementioned WordPress General Settings. There was no change in Secure Invites. Still got the same error in the source.
I also tried downgrading to Secure Invites 0.8.5. No change. However the source error was gone. Guessing you hadn’t implemented it yet 😉
I’m having the same issue. The only difference is that I’m letting the function detect the image type automatically instead of specifying the type, and I’m only getting one error consistently, “Data is not in a recognized format.”
