Why am I not able to see Advanced Search?
|Knowledge Article Number||000220446|
|Description||In Summer ’15, we replaced the rich text editor in HTML area home page components with a new version that supports more markup but does not allow HTML to be manually entered. This will impact the ability to view Advanced Search.|
|Resolution||Please ensure that you do not have custom home page component of type HTML area as they are not supported with Summer '15 release. You can find the details of this change here.
Note: When Chatter is enabled, global search and feed search are enabled, but sidebar search and advanced search are disabled. See Limitations for Search in Salesforce Classic for more details.
