Am I the only one that get these really annoying Invalid Captcha Code Errors when actually, I didn't get it wrong?
I restock a fair bit, and I don't think I've ever gotten that error when I knew 100% I was right. Sometimes part of the word is cut off, but you can't even tell. Like, it might look like "fun" but there's a 'd' lurking just outside of the frame. You also have to input the codes in lower case, so if your capslock is on that'll give you the error.
@ sakurra_kaze Do you have multiple tabs that are in a shop?
