Okey I’m going to create a video
Thanks for your answer.
We’ve been created with ACF plugin. All custom fields are on the same single post page (we need it).
This is the Query Monitor plugin result:
1,24S 69.258kB 0,1037S 87Q
There’s no problem with the queries. The malfunction appers on rendering process, there are any slow javascript blocking the load page.
Greetings
