WordPress Membership Plugin
Further update – If I login to the Membership Plugin using Chrome it allows me to change the “Free Membership Level ID” field with no problems. When I use Safari the ID field always reverts back to Admin Username. I have tried removing all the plugins, but this didn’t help. Editing the field using Safari – private window worked also.
I tried a local install with the twenty sixteen theme and all browsers worked OK. I am currently using the Divi theme, perhaps this could be the issue?
Any help or advice would be great – many thanks!
