I’ve upgraded from OC3 to OC 4.0.2.3, by cloning my website with ‘kitconnect’.

Now I’m trying upload using the OC installer.

Extension installer / click Upload / Select file from downloads folder on my computer.

Then a small pop up window appears with my website address.

Nothing is downloaded, nothing works. Why?

Some downloads work, but not others.

I’m struggling with PayPal install and now X Fee/Discounts pro

SEO URL Generator installed fine.

It’s very frustrating not knowing why some work and others result in a pop up with my website address only.

Any help is much appreciated! Thanks!
