Wp Residence is compatible with iHomefinder optima express idx plugin (http://www.ihomefinder.com/products/optima/). Just need to go into Theme options -> Advanced and set “Use Optima Express plugin” to yes in order to avoid any conflicts.
COMPATIBLE means you can use the plugin as it is with the theme, without conflicts. Â The properties added through the plugin can be managed only with plugin features, options.
