Error: Cannot connect to the database host.

We have a user, that when they try to publish, get the following errors:

- We have quite a few other users, and this is the only person I am aware of with such problems.
- I checked their publishing information, and it is successfully able to "verify" the publishing location.
- I assume that much of the information has been lost, unless restored from a backup?

Any information you can provide to help look into the issue would be appreciated.

Thanks,
- Brad

Did user change publishing location recently? Probably this article explains this case: http://kb.odin.com/en/1811
For now, it is possible to to restore it from backup or try to copy modules database from old location.

We restored the site from backup, but this did not correct the issue.

We were forced to restore a copy of their sb_modules.php file from our own personal backups. It seems that this file may have been corrupted, but I don't have much more information in regard.
