Failed to download package. Download it and install manually from https://www.j2store.org/download-j2store/j2store-v3-3-3-20/com_j2store_v3-3-3-20-pro.zip?format=raw&dummy=my.zip.
So I try to go to that URL, and I get a 404 error.
Every copy of J2Store version 3 seems to be gone from the internet. Please help.
