Problem:
The Wordfence Security plugin is preventing Graphene General tab from saving. No other tabs are effected by Wordfence.
Solution:
I went though last updated plugins one at a time and one as soon as I deactivate Wordfence, Graphene options worked. To update Graphane, deactivate the Wordfence plugin, update the Graphene General tab data and reactivate the Wordfence. Hopefully this will help someone in the future.
I don’t if this information you find this helpful in future updates of Graphene.
Thank you, Syahir and Kenneth for the free support.
