I edited index.php in a copy of the default theme (v. 1.4.3.3). I made several code errors, and decided to revert back to the last working copy of index.php. When I uploaded the original file, Firefox returned a mostly blank page with only a zero.

I then changed the active theme back to default instead of my copy of default but the error persisted.

I called my hosting company and was told that there was no database configuration file. Is there a way to fix whatever I did or should I delete the database, delete the directory where I installed ZenPhoto, and then start over with a clean installation?

Thanks

The database config is within the config file within /zp-date/. No way that editing a theme can cause this actually. As a basic rule if you get blank pages there is an fatal error and you need to look at your server error log to find out what.

Thanks for all of your help. I looked back through files after your response. Sorry to bother you with a stupid error on my part. I obviously shouldn't edit files in the middle of the night if I can't sleep!
