I added an image to my signature and then didnโt like the way it looked in the forums. So I went back and deleted the image code and added text. Then when I posted again, the image was still there instead of the new signature. Deleted everything on the signature page. Image still there in the forums. Cleared cache. No help. Signed out and in. No help. Even looking at the forums with a different browser or a whole different device, itโs still there.
User dashboard > Forums > Forum Image > "Remove Image."
It's right by the Set Preferences, just much smaller text and easy to miss.

Nope, still there, but thanks for trying. I didnโt add it originally as a forum image, just put the code in my signature, which Iโve done often and been able to delete without issue.
I just tested and was able to change and then completely delete my forum signature with no issue or even delay. Did the signature ever update for either of you? If not: Does the preview on the signature page accurately update?
