I screwed something up when deleting sample content blocks I was creating with the marketplace add-on "designer content". The block test_product is something I created, but I deleted it off the server, so I am not sure what to do now. I tried to start over and now when I try to add a block, ANY block, this is what I get...

Warning: require_once(/var/www/clients/client2/web8/web/concrete5.1.6.0.2/concrete/blocks/test_product/controller.php): failed to open stream: No such file or directory in /var/www/clients/client2/web8/web/concrete5.1.6.0.2/concrete/core/libraries/loader.php on line 205 Fatal error: require_once(): Failed opening required '/var/www/clients/client2/web8/web/concrete5.1.6.0.2/concrete/blocks/test_product/controller.php' (include_path='/var/www/matrix.matrixprovenpos.com/web/concrete5.1.6.0.2/libraries/3rdparty:/var/www/clients/client2/web8/web/concrete5.1.6.0.2/concrete/libraries/3rdparty:.:/usr/share/pear:/usr/share/php') in /var/www/clients/client2/web8/web/concrete5.1.6.0.2/concrete/core/libraries/loader.php on line 205

Any ideas? Thanks so much!
