I'm new in Drupal and new here, I tried to find a solution to my problem, but I didn't find the solution so I will write here...
When I click in "save and continue" in the page "Install Profile" (to configure my drupal), appears this message to me:
Fatal error: Call to undefined function field_attach_load() in /opt/lampp/htdocs/drupal7/includes/entity.inc on line 316
What should I do??? Anyone?
