Submit Button Disabled

I submitted a solution of glitch and gone to next challenge, there the submit button is disabled
i tried to login in to my account in an another browser but still the submit button is locked for me what should i do.
not only this challenge but all the other challenges are also blocked for me.

you have not added a link to submit, the button should activate once you submit a link

Thank You ,
i know it is a very lame question , i don’t know what i was thinking i had fought with it for 1 hr

Thank you .
