Knowledge article content isn't displaying for a userIssue Some Knowledge articles' content is not visible for a userReleaseALLCauseAfter a thorough investigation, this behavior is a result of the users' customization of a OOB (Out of Box) UI Page plus an additional custom UI Macro.Resolutionit was found that the behavior seen stems from fields referenced in two customizations: kb_view_customer UI Page /nav_to.do?uri=sys_ui_page.do?sys_id=1f5e464b0a0a0b3200dbbe75f65063e4 kb_view_custom UI Macro /nav_to.do?uri=sys_ui_macro.do?sys_id=7edf96502d2030405736db840fdcb970 Support Engineers are experts in OOB functionality and specialize in OOB break-fix behaviors. The debugging and implementing of custom code are not in the Engineer's area of expertise, unfortunately.Therefore, it was recommended that the user kindly review these customizations with the team who developed them as that team has a firm understanding of what the customizations are trying to accomplish as well as a more intimate knowledge of the users' environment.
