I loaded S2MEMBER Plugin and later deactivated the plugin.
When I did the "deactivate" - Dashboard refreshed ... then gave me a white page of death stating it could not find page.
Tried seveal attempts to go to thru the back door of the wp-admin or wp-content and would still revert me to blank screen of death ..
Finally had changed the .htaccess .. with the .htaccess-preinstall and the site came back.
HOWEVER, when I do go into Dashboard then to PLUGINS => Installed Plugins - I am sent back to my home page...
I have yet been able to figure out where the source of the problem is and would like to get some idea what all S2MEMBER changes in WordPress.
