You can experience a weird behavior when trying to use 'Submit ticket' or 'Ask a question' links in your LiveAgent installation. The result pages are always default 'Page Not Found 404' pages... This happens because the server cannot find the LiveAgent files because of .htaccess. Some servers need an extra line of code in the .htaccess file of LiveAgent to make it working properly.
Check what directory is your Live Agent installed at, and add this line of code with the directory name:
RewriteBase /_directory_name_/
You can place this line just below line:
RewriteEngine on

NOTE: As this is a custom change of original file of your LiveAgent, remember to do this when updating LiveAgent.
