NFT Collection not loading

I’ve noticed that the plugin is calling API V1, but it seems that since ?last?Dec 14, 2023?it is deprecated – read?here. I think that the plugin code should migrate to the new V2 endpoints which can be found here:?https://docs.opensea.io/reference/list_nfts_by_collection

Hi Emanuele,

I fixed this by updating to the new v2 endpoint in /wp-content/plugins/nft-gallery/inc/shortcodes.php and can now display NFTs from a single wallet Ethereum address. To show a collection needs a little more work, which I would be willing to put in, if the plugin author will add me as a contributor to the plugin.

In case you wanna give this a shot, here’s the updated shortcodes.php code:

<?php
/**
* NFT Gallery - shortcodes.php
*
* In this file,
* you will find all functions related to the shortcodes that are available on the plugin.

But bear in mind that this only works with Ethereum NFTs, probably because the v1 API did not support other chains. Those could be added easily to the plugin configuration page, though.

Finally released a new version of the plugin that supports v2 of the OpenSea API.
