Greasy Fork

I can browse greasyfork pages, install scripts, post discussions, login/logout... But I just cannot post script update. Everytime I click the 'Post new version' button I found this page keep loading for a really long time, and finally got this:

Just now I succesfully posted a new version using firefox, but chrome is unable to do that.
I don't know how does this happen.

May depend on the content of the script you're trying to post. If there are errors in it (or even something unexpected) it could cause this.

I don't think that's the reason, though the the content of the script I'm trying to post via chrome is exactly the same as the content I posted via firefox .... However, thank you for answering:)

Firefox and Chrome may post things in different ways. Also possible there are some cookies set in one or the other that are affecting things. If you upload here what you're trying to use I can try it myself.
