Urgent help please

How come I am not allowed to access my signature?

I'm getting this message:

WellingtonCats, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

Do you have to be a paid suscriber now or something?

Please let me know so I can change my signature with respect to Cathi's family.

You should be able to access your signature. There was an incorrect setting.

Thanks Deb. I changed it and it was fine for about half an hour and then for no apparent reason it stuffed up and it wasn't the same font or colour anymore, I've fixed it now. I'll see if it happens again.
