Configuration check warning:
The TS setup variable plugin.tx_realty_pi1.pages is empty, but needs to be non-empty. This value specifies the list of PIDs that contain the realty records to be displayed. If this list is empty, there is only a message about no search results displayed. Please correct the TS setup variable plugin.tx_realty_pi1.pages in your TS template setup or via FlexForms.
When that is done, please empty the FE cache and reload this page.
The configuration check for this extension can be disabled in the extension manager.
