I have recently come across an issue where my Localhost Apache server (and/or MySQL server) will interfere with some random websites.

Most recently I discovered the localhost was causing issues on a Joomla website were a single component would throw a 404 component not found error.

since 99% or more of the web continues to work correctly I assume there are 2 primary causes and 3 possible solutions.

Causes 1. code issues with the website/Joomla component 2. localhost apache configuration issues


  1. Fix the code issues (if it's your site/component)
  2. fix the issue with the localhost configuration
  3. stop the localhost server when your surfing the web

I need guidance on what in php code for a Joomla component would cause such issues, and how to fix those code issues. I would hate to see someone happen to have a localhost instance running and have an issue with one of my sites.

Changing Apache from port 80 to port 81, or anything else, should solve this issue without haveing to stop Apache.
