My client is running revo version 2.3.3 (I know I need to upgrade after this issue). The website is not displaying properly: http://www.skywardltd.com/
According to the client, they were working on the contacts page only adding a new employee before their site went down. But the website looks like there is a larger issue at play, other than just a POSSIBLE messed up HTML page edited from a non-webmaster in the admin resources page tree. I do have all pages, templates and chunks backed up from a year ago.
The error logs have this many times over from 2016-12-28 - 2017-8-14:
/SERVER PATH HERE/xpdo/xpdo.class.php : 3043) SQLSTATE[HY000]  MySQL server has gone away
Yet the front end of the website shows invalid certificate. The backup they have is over a year old, so I want to see if I can remedy this before contacting their hosting company about a possible backup. Where should I look first to see why this website is not showing?
