Help! I'm getting logged out.

Help! I cannot figure this out. I've had Grow installed for a little while now, but I can't figure out how to get the Grow plugin to stay connected to my site.

I log in (see the next screenshot), but it always reverts back to what you see above.

I'm not an advanced IT person, but unfortunately . . . I also can't really afford to hire one. Any ideas? I've searched through other posts on here, but haven't yet found a solution that worked for me.

I've tried:

- Turning off "minify" in my cache plugin (WP optimize)

- Making sure my Grow email matches my WP login email

- Uninstalling and re-installing the plugin

- Permanently uninstalling Shareaholic 

These are screenshots of my current cache settings in WP - Optimize:
