i have no access to the admin cp so i can't be much of help.
but check if you can login directly in the forum:
http://silvatales.mysidiahost.com/forum/
if you can then you can send silver a pm or open a thread in there in case she don't see this one, probably you will need to give her the user name you used and see if she can do something.
also a few days ago silver changed the URL of the main page to a custom one and that caused to not be able to login. for some reason if you try to logging from custom pages (
http://silvatales.mysidiahost.com/pages/view/explore) or daycare (
http://silvatales.mysidiahost.com/levelup/daycare) the site gives you an error, something like the page cant be found.
hope she can solve your problem soon.
