rev. slider, client pages to have bright images

Hello. I posted some questions earlier about the rev. slider, but so far I have not heard from you guys.

– the rev. slider crashed my site, and I had to work with my site host to disable the plugin so that I can get back into my site.  However, I want to reactivate the slider, but I’m concerned that it might cause trouble again.  How do I fix this?  I sent you some of the error messages in my previous tickets, but got no reply.

The admin. credentials that I sent are unchanged; please take a look and see how you can help.  I still can’t get my users to add friends, groups, topics, etc.

-Very importantly, the “members”, “community” and “activity” pages are all blank, and they all default to the membership levels page.  How can I get members to see and add other members as friends, request to join a group, etc?

-Also, how do you change the client portion of the page, so that the images do not fade into the background, but are bright and full-focused like they are in other parts of the home page?

Thanks and look forward to a prompt response.
