Unable to open script: WA_Configuration.js
This one has eaten up a lot of time for me today. Working on adding file upload behavior to a data assist form. On the insert page, when I try to open the insert record behavior to make the proper change to the behavior, I got the following error message:
Tried disabling and re-enabling extensions. No go.
Then uninstalled, downloaded fresh copies, reinstalled and it worked for the insert page.
Then, I attempted to do the same to the update page and... get the same error message above.
