Problem: I need to know which Apache rewrite rules are being triggered, and possibly how.

Context: I'm trying to get a .xml request to rewrite to a .php script, all I'm getting is a useless message ([cgid:error] [pid 19515] (8)Exec format error: AH01241: exec of '/www/xml/v3/availability.xml' failed ). Apache version is 2.4.25.

What I have tried:

• add LogLevel alert mod_rewrite.c:trace8 to the top of /etc/apache2/apache2.conf and then sudo systemctl restart apache2 - this achieved nothing, nothing extra shows up in the error log.

• I also tried putting it inside the <Directory> of the <VirtualHost *:443> entry (sites-available & sites-enabled/test.conf), this also yielded no results (while it does have AllowOverride All).

• I also tried LogLevel debug

• I also tried rewrite:trace8 instead of mod_rewrite.c:trace8

you can just put a hash symbol # in front of each rewrite rule which will prevent them from executing, then one by one remove the hash symbols # until you find which one is causing the error.

The logs I were looking at were not the actual logs. There was a directive somewhere else setting the log location to another place. After finding the actual logs, I could see the debug information.
