Hi Stiofan,
I have just started today configuring Geodirectory and I have the same problem “Icons not shown on maps or popular categories”, but I am not a technical guy and I do not understand how to apply the patch that you mention to solve it.
I have installed the version 1.3.9, which is the version available for download in WordPress.org, but the patch mentions version 1.4, which I do not know how to get.
Thanks for your help.
Regards.
J.O.
