I've got your plug-in already installed ( the newest version of the Next Gen Gallery) but after updating The Word Press to 2.9.2 version this plugin generates errors ( "Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.")as given below:
- I can NOT edit miniatures
- I can NOT add gallery to the web page
How to solve these problems?
When I try to uninstall and install again , still the same , it does not help
