you should check it with your system admin or our managed support since there will be needed package reinstall and maybe mail server rebuild required.

I would like to go for your support. Can you guys install the Letsencrypt SSL certificate on my server which will probably solve these issues?

E-Mail / Cannot receive emails

Hello,

During my failed attempts to install Letsencrypt certificate I have deleted my certificates created when I firstly installed Centos Web Panel. Now I've noticed that I can't receive any emails, however I can successfully send.

Here is an outpout of my mai llog:

As you can see, the /etc/pki/tls/certs/ca-bundle.crt is missing. Is there any way to recover it? Should I generate a self signed certificate and rename the file as ca-bundle.crt?

Thanks for the help! I'm losing clients because I can't read my emails

I already use gzip compression, even just installed WordPress websites have a pretty long load time.

SSL / Re: Short Let's Encrypt guide on CentOS 6.x

I wasn't able to install Let's encrypt using this guide. I don't know why but I had to update .key .csr and .bundle files manually and still, it appears that the connection is not secure. Anyone managed to get it working?

CentOS 6 Problems / WordPress performance issues

« on: March 13, 2016, 03:30:18 PM »

Hello,

I noticed that the WordPress websites I host on my CentOS 6 VPS have performance issues (slow load time). Do you have any tips on how to improve performance for WordPress?

I also have another website built with PHP and it works great, this problem seems to be only for WordPress.

Here are my VPS stats:


My Web Server is running on Apache & Varnish Cache & Nginx Reverse Proxy.

Thank you!
