Admin page blank after upgrade from v13x

[itsupporter]

When trying to open the admin page, it is completely blank.
The URL is "http://cncspareparts.se/adminGG6&3eE/index.php".
We have also installed the correct and latest version of the Swedish language pack.

This is a piece of the /public_html/adminGG6&3eE/includes/configure.php

/ NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
  // these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
  define('DIR_WS_ADMIN', '/admin/');
  define('DIR_WS_CATALOG', '/');
  define('DIR_WS_HTTPS_ADMIN', '/admin/');
  define('DIR_WS_HTTPS_CATALOG', '/');

Explain how you upgraded.
What process did you follow? What steps did you take?

[itsupporter]

I followed the recommended steps in the pdf "implementation guide" in the v150-installation pack

So did this work properly in your temporary staging area before you did the upgrade to the live site?

So did this work properly in your temporary staging area before you did the upgrade to the live site?

I had not the opportunity to do this test due to an upgrade of php om my webserver. I had to upgrade without testing in a temp staging area.
What can be the trouble? The public homepage is showing alright, it is only the admin page that is blank. Any advice?

[DrByte]

Well, as a start, the configure.php file contents you quoted is from an old version of Zen Cart.
And, the admin foldername you mentioned doesn't match what's in the configure.php file.
So that's probably the first big problem.

These are the sorts of things that a staging area is intended for: a time and place for troubleshooting your problems while your live store continues to operate without downtime. That's why the implementation guide tells you to do that.

And webserver upgrades of PHP versions etc which make your store's software obsolete are exactly the reason one should do regular upgrades to stay ahead of server dependency requirements, so that you don't end up in urgent situations such as you describe. Just a tip for future.
