My site runs smoothly until I try and install a new plugin and activate it. Lately I've been getting this error
The website encountered an error while retrieving http://blissful-reviews.com/wp-admin/plugins.php?activate=true&plugin_status=all&paged=1&s=. It may be down for maintenance or configured incorrectly.
Error code: 500
After installing a plugin and activating it; the latest error occurred when I installed a Backup plugin. So I went into my database and disabled all my plugins so I could access my panel again, and reactivated the plugins I knew I had no issues with prior to this plugin and deleted this plugin. After doing that, I clicked on the Posts page and received

I have no idea why this keeps happening or how to fix it! It started doing this a lot after I attempted to install W3 Cache Plugin and couldn't get it to work on my site AT ALL even after following all the directions it kept breaking everything. So I went through the uninstall process and made sure all the files were cleaned out, but ever since then I have issues with installing new plugins and it breaking my site.
The actual site itself: blissful-reviews.com loads fine at least on my end so it seems all the issues are on the admin pages so I can't get into to blog etc.
It also seems to only effect the pages for Posts, Pages, as the other links work fine in the admin bar...
