Federated Experience Manager cannot be loaded if EXM is installed

  • After trying to launch FXM on Sitecore XP instance with EXM module installed, the spinner animation remains displayed indefinitely and the browser console shows the following error:

    "Uncaught Failed to data-bind: ProgressIndicator TypeError: Cannot read property 'attributes' of undefined" sitecore-1.0.2.js:2902
  • To resolve the issue, consider one of the following options:

    Be aware that the hotfixes were built for specific Sitecore XP versions and must not be installed on other Sitecore XP versions or in combination with other hotfixes that modify Sitecore assemblies. In case any other hotfixes have already been installed on specific Sitecore XP instance, send a request for compatibility check to Sitecore Support.
