This is a great File manager, might be a little large for many applications, but quite suitable where space is not an issue.
I've always been curious how we assign lxde-icon-theme to PCManFM-Mod.? There doesn't appear to be a config file which specifies which icon theme to use afaik.
While I'm not sure exactly how I managed to fix this, but after deleting all files in home & opt directories, I rebooted to a fully functioning PCManFM using ldxe icon theme!! some corrupted hidden gtk config file no doubt, oh well!!
Update!! I believe I found the answer in a config file named .gtkrc-2.0
