Hi guys,
I am using a theme for one my website. Website is a news blog, 10 days before suddenly website vanished and it gave me error "Error in establishing database" I contact my hosting provider, I update plugins, I update wordpress version, I install Wp-Cahche plugin, I optimize Website but still error is there. Sometimes website works perfectly and sometimes it takes too much time to load or sometimes gives me errors, like "505", "405", "error in establishing database" "server timeout".
I changed hosting server and they are saying error in js composer.
I tried everything but still failed.
Your help will be greatly appreciated.
Note:
(I am not much familiar with wordpress, I am a front end web developer)
