Steps to Reproduce

1. [First Step]
2. [Second Step]
3. [and so on...]

Expected behavior: [What you expected to happen]

Actual behavior: [What actually happened]

Versions

• osTicket 1.10
• PHP 5.6.30

Update: this seems to be happening when osTicket cannot connect to mysql, it seems it will try to send an email and that function uses _S(), however Internationlization::bootstrap only gets called during /setup/ ?

Just in case anyone else is encountering this issue... I had this issue on CentOS 7 running Apache - with SELinux, however the database was on a separate system.
To test whether your issue is with SELinux: setenforce 0 and refresh the browser. osTicket should now work fine. If this is the case for you, here is the solution.

SELinux is disallowing apache to create network connections, so simply allow them.

setenforce 1 # We want SELinux to remain on!
setsebool -P httpd_can_network_connect_db 1

Easy

In my case the error occurred due to the database engine being down.

[sundbry]

Despite the database being down, the problem here is that the email notification that the db is down fails due to this compilation error.

The function _S seems to come from the il8n module, but it's a bit complicated to trace if/how this function is actually loaded.

There might be a problem with DB connection! make sure your user has the password. root with no password can cause this error too.
