i have been having this trouble for a couple weeks now with gimp 2.8.
The problem is that all my extensions are gone when i try to save and wont even accept it when i manually put in extensions, the only one i have are gzip extensions and the .xfc to save as not even .jpg . now when i load by extensions it shows all of them so the problem only persists with saving and not loading. i have looked to see if i needed to download them but i have no luck in finding a download or plugin.
I have been trying to make a GIF file and it is irritating, any help will be appreciated, thanks
