Teresa,
I just added your termur account you've been using to post so you can post from either going forward and have the Active Subscription indicated on there.
As for the System - Cache plugin, I'd leave it disabled. It definitely isn't required, and while we're debugging, it's best to be disabled. I just looked around the front of your site some more and noticed you're using some RocketTheme stuff. If you have either the RokZipper or RokBooster plugins enabled, can you try disabling those. They have the same effect of caching the output of the page, and could be the problem. If disabling them works, we can help you determine more specific settings within each plugin to disable to get things going. That way, you'll still have the benefits of those plugins (which can increase performance slightly) while fixing the problems you're running into.
As for the line-return after the Privacy Policy line, that's not being done by JFBConnect. You're inserting the Privacy Policy in a <p> block, and then after that, adding the {JFBCLogin} tag. You'd want the {JFBCLogin} tag inside the p block for it to be on the same line.
Hope that helps, but keep us posted on any issues!
Thanks,
Alex
