Colour In Signature Gone Missing

[GregChapman]

Hi Hugo,

Since yesterday the colour has gone missing from my signature on my forum:
http://band-forum.2320619.n4.nabble.com/
embedded at:
http://www.muddybroadbluesband.co.uk/forum.html


Although it shows as it should in the preview on the Edit signature page:



I recall this happened for a period a few months ago, but then righted itself.

Hi Hugo,

Colour is back again!
Have you made changes at your end?

No changes. I don't know what happened.
