Pages for individual places give 404 error

I’m using WordPress v5.2.4, and Geodirectory v2.0.0.69. All required plugins are installed and up to date, as are the Multilocation and SocialImporter plugins. I am using a child theme of the Listimia theme but I have also tried with the completely unmodified GD Framework Child theme, with the same results. I have added no custom post types and other than importing about 1100 places from a CSV file, have done no customization. Most settings are still at their original values. All pages seem to work correctly except when I click on one of the individual listings shown on the search page, which results in a 404 error. The URL seems to be correct, as it is in the form http://mysitename.local/places/my-place-slug. Is there a setting I am missing somewhere, or is it possible that Geodirectory is incompatible with the Bedrock site template from roots.io, which does not use the standard WordPress directory structure? I really hope not, as I very much need them to work together, and this would be the first plugin I have found which was not compatible, after building many sites using Bedrock and Trellis. The site is still being developed locally so I can’t provide a URL, unfortunately.
