I realize that, after installing this plugin your wordpress getting so much slower. Not is like immediately but you can see after 2-3 days later..
That's right - the problem you can see is in: System StatusI can say I am running on my own server and It normally works like a charm (without this plugin), there is no limits on my site. And still after 4-5 days later I can see any page load takes 50seconds. But if I rename the folder of that plugin and fix it with old name (I mean disabling and reactivating it), the site works very well with this plugin. I couldnt understand why I am trying to dig in the codes but I cant find anything also I can see thats not rest api related.
