Addon domains utilize mod-rewrite to point to the correct location
since you are basically hosting two or more hosting sites from
the same account and need to differentiate them.
Now one problem I do see is in your domain paths ....
In Cpanel 11, the path for addon domains is:
Code:
/home/(login)/public_html/(domainfolder)
You may want to move your addon domain folders up one level
on your account and remove the extra "/folder/" from the .htaccess.
This will get rid of you having an extra subfolder showing up on all your
domains and any further addon domains you add should already be
setup correctly from the start.
