I've bene playing around with themes in my SMF installation, and noticed that when I clicked the red X next to themes in my control panel (to delete those themes) the MySQL entries were deleted for that theme but not the theme's folder on the server. Is it safe to delete this folder?
Also, I tried to upload a theme and got a mkdir error because the theme was in a subdirectory in the archive. The failed theme upload did not show up on my theme list in my admin panel nor did it create any MySQL entires, but the folder was placed. I deleted the folder and have had no errors, is this OK?
