I have recently moved a wordpress site to another server but it encounters problems like The plugin gd-star-rating/gd-star-rating.php has been deactivated due to an error: Plugin file does not exist. The plugin nextgen-gallery/nggallery.php has been deactivated due to an error: Plugin file does not exist. The plugin thesis-openhook/thesis-openhook.php has been deactivated due to an error: Plugin file does not exist. there are lot of pages on my site dependent on plugin's Help.
if you're getting that error when visiting your site , then Delete these plugins and you should be fine , then re install them
