I installed the dsIDXpress plugin and activated it with a free trial account. After setting up the IDX page and adding the IDX widgets to the custom IDX Sidebar, the sidebar on the IDX page does not show any widgets. I’m using WP 3.7.1 and WPEstate v2.0.
The IDX page is imported from dsIDXpress and the sidebar is the one you set for the archive pages in Theme Options. It’s important that in Theme Options – Appearance – you set Category/Archive Sidebar to IDX Sidebar then save.
Please let me know if this solves this. If you need help, you can also email me your website credentials at firstname.lastname@example.org
