Frequently asked questions
Find answers to the most frequently asked questions about Drupal 7 Custom Module Development.
- Q: gmap3_tools is not working the way I expected it to. What version of gmap3_tools should I be using?
- A: Use the free exercise file containing the version of gmap3_tools used for recording; the published version of the module on drupal.org has changed since recording and is not backwards compatible.
- Q: I attempted to run the Drupal site root from the project files, but the site isn't loading. Why not?
- A: The Drupal configuration file in sites/default/settings.php contains database configuration specific to the environment used to record the movie. This may be different than your environment. Edit the file and search for "windfarms" - you may need to change the database host, username, password, db name and port to match your specific environment.
