If I choose option Display position “after” that plugin works in php 8.1 (without [download-attachments] – tag) but that works only i normal pages.

I use that plugin in woocommerce and there the option “after content” dont show anything. To show the plugin in woocommerce I have to use shortcode [download-attachments] which work only in php 7.4

If I try to use some other plugin, working in php 8.1, I have to add attachments again for about 100 products!!!
