Sorry for the delay Tom, in the meantime, i had to use an alternative option (didn’t want to) but needed it to be working in the short term.
Anyway, i setup a new test page, added the “same” WP show post shortcode that was playing up before (looping), now it works fine???
mind you this is only a 5-minute test, but on a new page, i couldn’t get it to come up with the error again.
So I dont know? I really want to use it but not sure what caused it or if its really working permanently?
