A tip for the future if your site is business critical - don't ever work or play with the live site.
Get Lampp (XAMPP) and install on an old pc to act as a server.
We use a classic 3 stage development methodology...
1) Initial work playing etc is done on the dev (development) server
2) After initial development restore/implement on Test server
3) If and only if OK on test, install on production server
Yes this needs 3 identically configured servers but it saves a lot of grief especially if your site/system is business critical.
