^That stupid error keeps on showing up everytime I upload multiple files. Although it doesn't prevent me from uploading. Any plans on fixing this?
No, because this version of the site will be scrapped soon™ anyway. And don't currently know what causes it.
Wait, Iwara's getting a new look?
Try a different browser? The frequency of this problem is browser dependent, at least for me. Also, always click the captcha first of all whenever you see it, so you know it's done before you fill in the rest. (I have three browsers in my computers: Chrome/Firefox/Explorer. Whenever one makes trouble, I instantly switch browser.)
There was no Captcha prompt when uploading material.
