    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...

    Any suggestions?

    Normally you would just rename the plugins. Going into the db can be problematic. Do you have a db backup?

    @Kmessinger - I did a full site backup last night to prepare to transfer a few things around on my hosting package. I wasn't sure how to actually do a backup from phpadmin itself. When I try to rename plugin folders via FTP it doesn't seem to help the issue and the errors remain.

    I just deactivated all my plugins via the admin panel & started reactivating them one by one and refreshing the post/pages page to see if I could get the error to show up. Everything was fine until I activated the WP to Twitter plugin and the error showed up again. I deactivated and refreshed the Posts and Pages page and everything was fine.

    However, the WP to Twitter plugin was activated and working fine w/o issue until I tried to install a new plugin. Any ideas why it would now cause an error?

    What happens if you activate the WP to Twitter plug-in alone, without activating any other plug-ins? Does it still trigger the same problem?

    The error message you're receiving, up above, isn't really very helpful, so it's not giving any clues about what's going on, unfortunately.

    By any chance do you run the Twenty Twelve theme?

    I am getting this error all the time now on any plugin, whether I add it, activate it or delete it. I have had a working site, working plugins for months, years now, which I update regularly when updates are available. The only thing I have recently updated is the Twenty Twelve theme and ever since then I am getting Error Code 500 for theme or plugin changes. The only way to fix it temporarily is to rename the plugins or theme folders to something other than their default names, and then back again to get back into my website, else I get the 500 code, failing that code I am getting white screen and no access to admin.

    It makes no difference if I swap the theme.
    It also seems any plugin with wp- causes this error as well. (I also had the wp-twitter, wp-highslide loaded for months and months and they worked fine. Now the second I activate them it throws the error and all of the above has to be re-done.

    I am completely stumped as to what is causing this problem. I am running two other sites with no problems what so ever (using all the same plugins and they are working.

    Here is a typical error that I see all the time now. In this example I had just de-activated a plugin called Highslide Integration and wanted to delete the plugin. Here is the error:

    The website encountered an error while retrieving http://www.wilkinsonsworld.com/wp-admin/plugins.php?action=delete-selected&checked%5B0%5D=highslide-integration%2Fhighslide-integration.php&plugin_status=all&paged=1&s&_wpnonce=92c2d71513. It may be down for maintenance or configured incorrectly.
    Reload this web page.
    Press the reload button to resubmit the data needed to load the page.
    Error code: 500

    Just discovered I can't even update a post without the Error Code 500 appearing telling be reload the page.

    @Wilkinsonsworld - No I'm not using the Twenty Twelve theme, but I did recently update it because it showed as needing updated on my Admin Panel; this is all I've done recently aside from updating plugins that needed to be updated and then trying to install a new plugin (a backup plugin) which now works that the WP to Twitter plugin is deactivated.

    I haven't yet disabled all my plugins and just reactivated that one to see if it has the same error. I will do this shortly and report back.

    The same error that you're getting above is what I am also getting when I have the WP to Twitter plugin activated, but it only effects me accessing the Posts and Pages page.
