As positive side we can notice that were able to reproduce issue from our side: homepage opened correctly but once go to Archive Special Journal of Open Research & Reviews 1st & best or Archive Spec J of Pub Health, Nut & Dietetics 1st & best page waiting and no load,
but once we refreshed this page it loaded. Please refer to the screenshots:
So it seems the root of the issue is only on WordPress installation side. I have tried to disable all active plugins but issue still persist.
Once I switched both https://sjphealth.spparenet.org/ and https://sjorr.spparenet.org/ from “Total” theme to default WordPress “Twenty Twenty-One” theme issue was gone, even with plugins activated.
In this case we would suggest to re-install “Total” theme on both WordPrss websites or contact with theme developer.
