XF 1.5 admin.php - Due to Database work this function is unavailable

[PaulVon]

My forum was spammed with thousands of posts and they keep on coming.

When I try and access admin.php I get the error "Due to Database work this function is unavailable"

I have rebooted the server and this has not resolved the issue. The spammers are still able to post.

Any help would be appreciated.

Simply temporarily block all access to port 80 (or port 443 if running SSL) to your home IP address.

I have disabled access on port 80 except for myself. There have been no new posts for about an hour. Currently, I am listed as the only visitor. I do have the ability to permanently delete threads.

My CPU utilization is 0%

However I still don't have access to admin.php.

That doesn't look like a normal XF error response (but it could be). How exactly does this error show up? This could be an issue on your server/hosting. If nothing else try re-installing the files from your version upgrade again.
Also you need to check your PHP and SQL logs for any possible errors.
