Hi. I make nightly backups of /usr/local/sitebuilder as well as MySQL dumps of the database. Today, I noticed that I had left the previous version's folder on the server (we upgraded from Sitebuilder 2.1.3 to 3.0.2 a few months ago) and decided to remove the old folder. However, I made a mistake and deleted the wrong folder, Oops! I didn't really give it a second thought though because I figured that I could simply restore Sitebuilder from the most recent backup. The problem is though, that after restoring Sitebuilder from backup (and removing the old, version 2.1.3 folder as well), Sitebuilder no longer works So when the main page loads now, it is blank - and this is what is in the error log: PHP Fatal error: Call to undefined function sb_verifybrowser() in /usr/local/sitebuilder/htdocs/index.php on line 23 and if I go to the admin page, it is blank as well and this is what is logged in the error log: PHP Warning: require_once(admin/design.inc) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in /usr/local/sitebuilder/htdocs/admin/index.php on line 3 and sure enough, there is no such file: /usr/local/sitebuilder/htdocs/admin/design.inc So what happened? The backup was made using `tar cfp /usr/local/sitebuilder' - but files appear to be missing. Any ideas or suggestions would be greatly appreciated. Thanks.
