[Hummingbird Pro] PHP Fatal error: Unknown: Cannot use output buffering in output buffering displ

Hi,

I’ve got a problem with Hummingbird Pro. When it’s activated, 255 posts give an error 500. For example that one: https://www.***.com/***-nuisance-sonore/

The exact error is: “PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers”.

As soon as I deactivate Humming Pro the 255 posts show up OK.

I think the problem is not related to some latest updates, these errors are here for months but coulnd’t find the time to have a look.

Support access granted on the website :slight_smile:

Right now I’m gonna deactivate Humming Pro.

Best Regards
