We are working on upgrading to EXM 3.3 from 3.2. On my local sandbox, after performing the upgrade, everything appears to be good except for the fact that when I go to view a message from the manager screen, the page that loads is mostly blank displaying only the Back arrow button, empty drop down, language drop down, Save button and the Email campaign info label and table.
GlobalValidationService.js:2 Uncaught TypeError: Validation.create is not a function(…)(anonymous function) @ GlobalValidationService.js:2execCb @ require.js:1650check @ require.js:866(anonymous function) @ require.js:1113(anonymous function) @ require.js:132(anonymous function) @ require.js:1156each @ require.js:57emit @ require.js:1155check @ require.js:917enable @ require.js:1143init @ require.js:774callGetModule @ require.js:1170completeLoad @ require.js:1544onScriptLoad @ require.js:1671
We have checked the log files and have not been able to find anything pertaining to this issue.
Sitecore 8.1 (rev. 160519)
When a new Sitecore instance is installed with EXM 3.3, it works until we sync and publish our Sitecore content and our Visual Studio project. However, deleting our custom assets (js, css files) doesn't appear to affect any change.
This problem appears to affect both pre-existing e-mails AND e-mails created after the upgrade.
After the suggestions, I have tried copying all of the files in /sitecore and /sitecore_modules out of the package and into the site and it does not fix the problem.
