WordPress is amazing and I am a big fan of it.
But the version 5.3 brought me a big problem with its new feature for auto-scaling down huge images.
I am trying to disable it with the following filter:
add_filter( ‘big_image_size_threshold’, ‘__return_false’ );
But it is not working, I still get an error for whatever image I upload to the server.
Same happens with the recommended plugin. It’s not fixing the error.
What error?: Postprocessing failed, please scale your image under 2500px.
I did clean the browser cache, set PHP version to 7.2 and activated mbstring.
