Hello, I installed my drupal test site for www.tata.fr I put into production a few weeks again later without worry. Then later I added a subdomain www.toto.fr (so this is a proceeding in multisite drupal) in the same instance as the first. Now I want to put my subdomain in production but it is no longer called www.toto.fr but www.titi.com production so I exported my DB I have replaced all www.toto.fr by www. titi.com this in my tables and then I put the directory of my subdomain in tata /sites/titi.fr. I created my apache2 virtualhost file and is ok. Except that when I was www.titi.com I have the following error: Warning: Invalid argument supplied for foreach () in / var / www / tata / includes / theme.inc on line 443 Warning: Invalid argument supplied for foreach () in / var / www / tata / includes / theme.inc on line 448 Warning: Invalid argument supplied for foreach () in / var / www / tata / includes / theme.inc on line 443 Warning: Invalid argument supplied for foreach () in / var / www / tata / includes / theme.inc on line 448 An idea? Thank you
