My store quit working - blank page

Sorry it took so long, I'm out of town. However I was able to get this fixed for you.

Whenever you have a blank page, the first thing I do is turn on error messages with this code on the top of the page:

<?php

ini_set("display_errors",1);

?>

This displayed an error with a missing image: installed.png

That is an old error that we have fixed in the latest version where it gets identified as a malicious file and deleted. The solution was to update the theme_open.php file. The site is working now.

Thank you for fixing that. Now my admin pages are blank.

You had some blank lines on the bottom of your Connection file. They were preventing sessions from saving and redirects from working. I've removed those blank lines and the admin site seems to be working now.

Thank you! That is resolved and now the forgotten password is not sending emails out.

I put up a simple email test page and can't seem to get your server to send emails. You may be able to send this to your hosting provider to see if they can tell you what might be wrong:

https://performancehorseshop.com/emailtest.php

It may be that you have to use a valid email address from your performancehorseshop.com domain. I see the from address doesn't match the domain in your settings and I didn't know a valid email address to test with.
