While executing onLoad in Design Notes_onOpen.htm, a JavaScript error occured
Here’s how to solve this problem. It’s an internal javascript problem within dreamweaver, follow the troubleshooting instructions below and everything should start working as normal.
Basically just find that filecache.dat file and delete.
Delete FileCache.dat files from the Dreamweaver user configuration folder. I actually renamed it, because when you delete…anyhow
Delete the WinFileCache-7A9586CB.dat, MacFileCache-BFE7CE2E.dat, or FileCache.dat file from the Dreamweaver user configuration folder. It is recommended to delete the FileCache.dat file if you are experiencing a JavaScript error related to “dwscripts” or if you are receiving a “translators were not loaded” error message. The string of characters after “FileCache-” may differ on your machine. The location of the FileCache.dat file depends your operating system and your version of Dreamweaver. Note that on Windows, the Application Data and AppData folders are hidden by default, so verify that your Windows Explorer folder options are set to View Hidden Folders.
