HTTP error 500 after migration

Question

I was able to successfully take a back up of D7 site and then restore to target D7 site. When I visit the site, I get an error

This page isn’t working. ...com is currently unable to handle this request. HTTP ERROR 500.

Added the code in settings.php:

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

Fatal error: Cannot redeclare views_views_plugins() (previously declared in /home/.../public_html/sites/all/modules/views/includes/plugins.inc:15) in /home/.../public_html/sites/all/modules/hjhkjhj/views/includes/plugins.inc on line 402

How can I fix the error to bring my site back up?

Answer 1

You need to run YourDomain/update.php and here you can find why.

If the problem is not resolved and (hjhkjhj) is a custom module, then you can't have the same function with the name twice. In your case views_views_plugins.
