On sites with many properties, the AI Concierge settings page can show a critical error, or the chat can stop responding.
Why this happens. In HomeRunner AI Search Enhancer versions before 1.114.0, rebuilding the AI’s property index on a large property catalog can exceed your server’s PHP memory limit. The index is cached and rebuilt periodically, so the error appears intermittent.
What to do. Update the HomeRunner AI Search Enhancer plugin to version 1.114.0 or later from Dashboard → Updates or Plugins → Update. Version 1.114.0 rebuilds the index in small batches, which resolves both the settings-page error and the related chat failures. You do not need to change any settings after updating.
