Another thing that happens to me and it is very strange, is the same website that I have in a subdomain within another server, and there the failure does not present me, but on the server of the main domain it does.
This is that i have installed on my site:
-Apus Framework
-Bookly
-Bookly Pro (Add-on)
-CMB2
-Contact Form 7
-Duplicate Post
-MC4WP: Mailchimp for WordPress
-McPopup – Popup Form for Mailchimp
-NextGEN Gallery
-Ninja Forms
-Page scroll to id
-Slider Revolution
-WooCommerce
-WPBakery Page Builder
-WP File Manager
-WP Fastest Cache
The exact same thing happens to me, the only way to keep my site active has been to remove write permissions to the WP-LOAD file.
But in doing that I have seen the website load too slow. each section takes about 20 seconds to open, also within the wordpress panel.
Please someone who can help us with a solution to this problem.
