Ok so i randomly decided to get a new signature but it doesn't work
The video shows whats happening

 

That problem happens when your signature is too long. The signature length includes URLs and BB code formatting.

 

How do i do then :[ ???

 

When your editing it, after you press save changes, keep pressing it about 10 times and then refresh your browser, see if that helps

 

Still doesn't work!

 

Find a signature that's URL is smaller... :/

 

I had this problem too with mine.
They seem to only allow signatures that take up to about 3 lines of text maximum. Maybe try re-sizing the image in photoshop.

 

You have come to the right place my friend ;)

There's a letter limit.
