How to clear my ignore list?

Quote from Moshe1010 : I don't know why but this is not happening. I have 300/300 when I'm ignoring a new thread and doing refresh to the page afterwards it's staying there.

Quote from nakickit : Same here

If you're at your max ignored threads and your oldest threads are not being knocked off when you add a new one, then something may be broken on SD's end.

Or maybe it's sticking in SD's server's or your cache somehow. After you ignore a thread, try either clearing your cache to see if that's maybe what's happening, or maybe try hitting ctrl+f5 to do a hard refresh.

Unfortunately there's no 'button' to use to clear out all of your ignored threads list at once. However, while you're on your ignored threads list page, you can click the little gray ignore/unignore button that's to the right of each thread title in your list and unignore each one that way.
