When using the WP External Links plugin, pages with facets will display a “FacetWP was unable to auto-detect the post listing” error after interacting with a facet or pagination. This is a known bug within WP External Links.

The following will prevent problems with FacetWP:

  1. Go to WP External Links’ settings page, to the “Exceptions” tab.
  2. Uncheck the checkbox after: “Apply settings on: All contents (the whole page)”.

The result should look like this:

Unchecking this setting skips processing content in AJAX requests. The authors of the plugin plan to add an extra setting for “all content except AJAX” in the future versions to help alleviate this issue.
