I am using below spec:
* Linode VPS
* Ubuntu
* Apache with Nginx reverse proxy
* Multisite with 1,000+ sub sites (Could that be the problem?)

Would these spot some light on the issue? Sorry that I do not have other test server to show this. Thx.

Probably is a bit late, but hope this helps (https://blog.centil.co/2016/08/14/how-to-fix-the-error-establishing-a-database-connection-in-wordpress/). Might be related to XMLRPC attack or max_connections issue

Hi, I got the same problem too. Anybody has an answer for that? Or WP-Encrypt plugin does not support that and we’ll need to do it manually? Thx!

Hi govpatel, I’ve set the permalink back to default (Verified that by clicking post link show default format https://192.163.194.212/~myhero88/?p=123). I’ve also rename the .htaccess file to something else. Anyway it still not able to access style.css

Hi govpatel, both WordPress address and Site address in Settings>>General are pointing to https://192.163.194.212/~myhero88

Yeah, I plan to use my domain name once I am able to setup the site correctly using this temp url. Although it is a temp url, I guess it should be working too.

Hi govpatel, I believe I need the .htaccess file cause I am using custom permalinks.

Hi ladober, yeap I uploaded the website from local server. Anyway “View Page Source” shows that it is pointing to a correct style.css file as below, just that it couldn’t load it.
<link rel='stylesheet' id='twentythirteen-style-css' href='https://192.163.194.212/~myhero88/wp-content/themes/twentythirteen/style.css?ver=2013-07-18' type='text/css' media='all' />

Since it is working locally, could that be some issue with .htaccess, apache setting or others?
