[Plugin: WP-Property – WordPress Powered Real Estate and Property Management] Out of memory errors

I’ve got WP Property running on a client’s site (https://mystarfish.net) and am getting lots of random Out of memory errors: https://mystarfish.net/6-bedrooms. I’ve been in touch with the web host and they are saying that the plugin is too memory intensive for their setup and that they won’t upgrade the memory on the server.

They are suggesting either to get another plugin or to move to a dedicated server, the latter of which seems overkill frankly. Does anyone have any practical advice that I can take please?

Thanks

Rob
