I can't install new modules. The install link not appear on the page of the modules. what should i do? Please, help me.
Hi there Emmanuel:
You have 2 ways:
1 - Enable the Update manager (a Drupal Core module that is included in your install) and it will show the UI in the backend.
2 - Install the modules manually by going to Drupal.org, downloading the module and extracting it in the sites/all/modules folder.
