S2Member making site not visible

I had s2member working perfectly, then it was deleted from my Wordpress, possibly a conflict of some sort. Tried to reinstall. Did not work. Went as far as to delete all of Wordpress and start over. Now when I activate the plugin the entire site, as well as the dashboard does not load.

I have to disable s2member to get the site to load again.

Any ideas on what could be causing this and how to fix it. A clean install of s2member may be my best bet, but what all needs to be deleted from the server?

If your PHP version is 5.3.3 or 5.3.29, the newest s2M version (160423) will not works. Use older version of s2M, until the team fixes it.
