Apache – An unknown filter was not added: DEFLATE

My ‘apache_error.log’ was logging an error ‘An unknown filter was not added: DEFLATE’ for every request. This is how I resolved it.

  • Open httpd.conf in C:\xampp\apache\conf went to line 93 and removed the # before the line LoadModule deflate_module modules/ (using notepad)
  • Restart the apache.
