This plugin is incompatible with MyBB 1.8.29

I really need an RSS feed posted on my private forum for myself why is RSS feed to post not availible for My BB upgrade?

It's not available because it wasn't updated - plugin authors aren't forced to update plugins for new versions, and this plugin is about a decade old.

Have you tried this one on the Extend site instead? https://community.mybb.com/mods.php?action=view&pid=294
