I have been having real trouble with GD Star rating recently. Firstly, the plugin simply 'vanished', depsite all the folderd still been accessible via ftp etc. It also wouldn't let me re-install it.
It's no big deal as such as the website hasn't officially launched yet anyway.
So, I manually deleted all the folders via ftp and re-installed via wordpress. It still didn't work and I got the following error messages ....
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot instantiate non-existent class: gdsrdefaults in /homepages/42/d284366774/htdocs/wp-content/plugins/gd-star-rating/code/class.php on line 103
Can anyone help? Many thanks.
