Furry stuff, oekaki stuff, and other stuff.

I might need a link to your board to figure this out. If both the applets (Java) and the canvas preview (Javascript) are not working, this sounds like some kind of server-side issue. Some servers won't serve JAR files properly, and tracking software can break the board's Javascript (even if your site does not have ads).
I just installed my Wacintaki 1.3.14, and everything works perfectly. The comments, upload, banner, permissions, registration, and everything work fine, but the "Draw" feature does not work. The applets fail to load on all browsers I have tried; there is a red "X". My brother also tested by going to the site on his computer, and he got the same results. It is not a problem with my Java because I have had no trouble whatsoever loading oekaki applets in other sites.
I'll also note that when drawing, the preview for canvas sizes do not work.
