Paul,
I tested v3,8,2 yesterday on another site and it was not working but this was an installation from 4-5 days ago. I am sorry but I am not a tester for your software. It is your role to test it first.
Can you please confirm and send a screenshot this version opens up properly on J4 site, and then I have no problem to install and test it on my site. I have already wasted enough time trying your new version and reisntalling old ones.
I also do not understand why you ask me about v3,8,2 and do not fix/test v3,8,3 ?
Arthur
