There are a few things that I've seen users have issues with when it comes to moving between accounts. Depending on the way your script is set up, you may be having an issue with absolute path. That will be different than what it was previously if you've changed accounts. Another common issue that people run into is PHP version. You'll want to make sure that you're either using the same PHP version in your new account or that all of your website's scripting is created to function on the version the hosting account is currently using. If those suggestions don't help, it may help to provide additional information on where this issue can be seen (including URLs). That may help others respond.
