Hi Bj?rn,
Thank you for taking the time to reply!
We are hosted on wpengine and are using these guidelines for our webp express plugin config options.

I am 110% certain that the settings got auto changed and I’m not sure when. I rechecked the my settings against the wpengine ones and they were not aligned.
The option “Alter HTML” was checked, when it shouldn’t have been.
This problem has been remedied. I should have rechecked this. I apologize.
