I have installed a Drupal+Civi test site, with same software level as my production site (Drupal 7.54 / Civi 4.7.16).
To be able to make real size tests, I want to have identical DBs on each site.
So, I have copied both prod DBs (Drupal and Civi) into my test DBs (using phpmyadmin / Copy structure and data + DROP TABLE).
Tables now seem identical (statistically : I have no real comparison tool)
I have updated settings.php with the same table "prefix"
But when I open the test site, I get an error : "Fatal error: Call to undefined function webform_menu_to_arg() in /home/bapaparoisse/www/dev/includes/menu.inc on line 824".
I must have missed something, but what ?
Any suggestion is welcome
