About point 1, I tried to insert the snippet provided by yevhen in the post you mention but it does not work. There is no randomization at all and listings still appear according to when they were added.
I inserted the php snippet directly into the Listings template. Am I doing something wrong or did something change?
thanks, but the issue is that the code itself does not work anymore. I know how to insert code snippets, but the code provided here Randomize listing order code still dysfunctional is not randomizing the listings anymore
If you have overwritten the template in HivePress > Template, everything should work correctly. Additionally, please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin, make sure that caching is disabled for logged-in users. Also, make sure that there is no caching on the part of the hosting provider.
