The host says a misconfiguration of the theme or a plugin is causing server timeouts. According to server graphs, there is high memory usage.
"We have parsed Nginx access logs and found 131779 connections for the past 5 minutes.
As you can see, there is most part of connections belong to your VPS primary IP 184.******

wp-admin/admin-post.php file is used for WordPress Generic Request (POST/GET) Handler, intended for form submission handling in themes and plugins."
How can this issue be fixed?
I read that NewsOnline is a deprecated theme, but I am not willing to change the website theme because of this.
I am working with my developer to solve this issue.
Please advise the possibility of premium support for this case.
