Hello Olga,
I got a response from my hosting.
They added the SubstituteMaxLineLength
It seems like one or more scripts are eating up CPU usage on this website.
I’ll make an observation this week. I’ll also try to contact Yoast. Elementor also has problem with my site.
If you notice, the site is loading too slow compare to showcasecarpet which is almost identical to onthecornermanila. Right now i just loaded the site on my browser and this is the usage. https://prnt.sc/74nTiQILG6Ic 🙁
