I can’t find the PHP error logs are on the ubuntu server.
Checking phpinfo() has “no value” for error_log. If I run a locate error_log I get nothing for the domain I am working with. This site is on a shared server, so I’m not sure I’ll be able to change anything in php.ini –
Where are the PHP error logs?
Then you need to ask your web host where the log file(s) are located.
It’s entirely up to them where and how each virtual host has its logs written.
