The document type “php” will not be added because it uses a file extension that is already associated with a prior document type
Effects: Dreamweaver 8, Dreamweaver CS3, Dreamweaver CS4.
When I installed the Drupal Extension for Dreamweaver I got the following error:
“The document type “php” will not be added because it uses a file extension that is already associated with a prior document type”
This occurs because you have previously edited the document types file to include .module and .info.
1. Navigate to your dreamweaver folder (C:\program files\adobe\adobe dreamweaver cs4\ or c:\program files\macromedia\dreamweaver 8\)
2. Under configuration\DocumentTypes you should seee a file MMDocumentTypes.xml
3. Remove the entry where you have added .module to the PHP section of the file (do a search for module).
4. Save the file and relaunch Dreamweaver.
