Help! Users unable to login

[Sarah L]

Our users are unable to log into our forum. I just tried to log into admin CP and got this message - but can't actually get INTO the admin section to do anything about it:

[[Template core/admin/global/globalTemplate is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

Any advice? Our forums are an integral part of our events and we're going to have to run one without it today.

Thanks.

Have you tried the steps there by switching to an unmodified theme and disabling all third party applications/plugins?

Recovery mode can be used to do this if you do not have access to the ACP:
