Issue posting with images

[Ashtonio]

Getting the below error when posting with an image. Not all images either, it'll work sometimes and won't the next. Below is the error that's coming up.

Any ideas?

Error posting:

Server returned incorrect thread/post id. threadNo: 0, postNo: 0

The backend (4chan) thinks you are a spammer. From what I heard from the people this happens when you are trying to create a new thread on some boards where you haven't made a certain amount of posts before that. I don't know the numbers and they are probably just speculation.

I probably need to add a message explaining this to that error message.

I know this sounds crazy, but I've noticed it only triggers when trying to post lewds on /vt/ board. Posting any non lewd picture works normally
