Is it possible that there is an issue with your database?

Did you change the password or location of it?

Or possibly something with /config/site.php? Although you have said you haven't touched anything, so I would place my guess on the database.

It is actually a clients site that I built and he doesn't touch the website outside of c5. My initial response was that it could be a database error but when he contacted his host they denied and said it was a php error. It seems to be a php error from the error message but I'm not sure what it actually is.

Thanks for your response

The reason I asked is because the ConfigStore constructor calls Loader::db() to get it's instance of Database. This is a static method call and seems to mean that Loader::db() is not returning a Database object.

Loader::db() checks a few things but basically it looks like it tries to get $server passed in or instead checks DB_SERVER which is defined in /config/site.php which would lead me to believe that DB_SERVER is not being defined in /config/site.php

This could be because the file does not exist. That the server does not have permissions to it. That it is not defined in site.php or probably something I don't know about. You might want to check the permissions of /config/site.php and then verify that DB_SERVER is set to an address just in case.

Thanks! I'll try this out and report back.

This is a stab in the dark. Maybe the host has changed the environment slightly, such as a change to php version or library? (I had an issue a few weeks back where a site host did a server upgrade that changed a perl library module; not a C5 site, but I had to do some fast work to get it live again)

did you ever find a solution?
