Can't upload gifs

[JukoThe10-Tails]

I don't know if this is an error, or I'm doing something wrong, but I can't seem to upload gifs at all. If this isn't an error than is it possible to add it as a feature or does anyone know a trick to do it?

Verify that the file is permitted in your LocalSettings.php file $wgFileExtensions
$wgFileExtensions = ['png','gif','jpg','jpeg','doc','xls','pdf','ppt','tiff','bmp','docx','xlsx','pptx','svg','webp'];
or that you have set

$wgStrictFileExtensions = false;
