Hi,
Our listing belongs to a WordPress Custom Post Type “Listings (acadp_listings)”. So, it uses the WordPress’ native WP_Query class https://developer.www.ads-software.com/reference/classes/wp_query/ to get the data from your database. When you enter some value in the “Keyword Field”, the value of this field will be passed the WP_Query search parameter “s” https://developer.www.ads-software.com/reference/classes/wp_query/#search-parameters
Looks like some plugin (or theme itself) in your website is creating troubles when the “s” parameter is used with the WP_Query.
Solution:
Please try disabling your plugins one by one to find which one causes the issue. If you are able to identify the conflicting plugin, enable the plugin back and check if the plugin has any settings to disable this behavior. If the plugin doesn’t provide any settings, please report the plugin author mentioning this as a BUG.
If the issue remains, even after disabling all your plugins, your theme should create the conflict. Please write to your theme author about this.
I hope this helps you!
Thanks
