Since the 1st of March of 2023, the following WebAPI versions have been removed from the system, so any website that was not upgraded before will no longer display property results.
V4.1, V4.2, V4.3 and V4.4
V5.0, V5.1, V5.2 and V5.3
If your website is still using a deprecated WebAPI version, speak to your web developer about upgrading.
