I uploaded new code. on loopart.xyz
Only the problem is that you can not test to mint 1155. it can be done only with one wallet address.
but 721 is for public and everyone is able to mint nft. but does not function.
my problem is that there was changes on ipfs publick gateway but even i point it to updated infura or pinata or our ipfs.csdoge.club it does not work.
besides it 1155 minting on out getaway but not on any of above. but does not mint 721.
this also related with moving from legacy to new environment.
you can check now lootart.xyz with no https protocol.
It is still the same issue - http:// redirects to https:// for that website.
let me check later it is too late already here
