The following script error may be displayed in the user's browser:
Message: Unable to get value of the property 'payload': object is null or undefined
The issue only affects clients using Internet Explorer - Chrome and Firefox are unaffected.
The issue appears to have been caused by an update to Internet Explorer since the release of Sage CRM v7.2 GA. Internet Explorer versions 9 through 11 are affected.
Installing a later patch of Sage CRM (such as Sage CRM v7.2e) will resolve the issue.
