Why, when I edit an album or photos text, do quotation marks appear as \ (e.g. John Doe\s Album)?
Your host has magic_quotes_gpc enabled in php.ini This causes form variables with quotes to be escaped with backslashes. Gallery tries to turn off this functionality, but in your case, this didn’t succeed. You’ll need to contact your host and ask them to turn this directive off, at least just for your site.
