I have two different instances of the same server (one for development, one for deployment), built independently but basically the same (same OS, same WordPress version, same content etc.).
However, I'm confused about the configuration: it looks to me like they're configured the same (except that the deployment server is told not to write errors/warnings to the browser).
Both configurations specify
ini_set( 'error_log', '/var/log/wp-debug.log' ); and that file is indeed created by both; however, on one server anything written using
error_log(...) goes to
/var/log/wp-debug.log whereas on the other server, such output instead goes to
/var/log/apache2/error.log (although PHP errors and warnings go to
I've tried playing with the defined values of
WP_DEBUG_DISPLAY as well as changing what
display_errors is set to via
ini_set(...) but nothing seems to make any difference.
Can I specify somewhere that I want the output of
error_log(...) calls to go to one or other of these logs? (I'd like the output always to go to the Apache
error.log because that extra information I want to use.)
