Dashboard access disabled after saving WP-Activity Tab 2 settings!
(with ''gravatars for profiles...'' selected - the only modification made in the Tab 2 of the WP-Activity settings)
Nothing works anymore related to users !
I deleted WP_activity folder from control panel, file manager, WP-content, plugins. No change!
Error message trying to access Dashboard or an user-related profile/page: ''Not acceptable"
What should I do????????
