Blog home & category pages are blank/no content using WordPress (fishpig)

Hello, Having issues with a site I just took over management for. There is work to be done for sure, but first issue is the blog/wordpress. It’s using the following: Magento 2.3.3 WordPress Integration 2.0.11.18

The main blog page (/blog) and category pages are blank, but you can still view regular blog posts.

I just updated everything in WordPress with no change and cleared all cache’s in Magento.

I know the site needs an update, but trying to get the blog up first, then update Magento etc. I was tempted to install the new version of Fishpig but it is a pretty big jump.

Any help/tips would be appreciated.

Thanks,.
