I create a joomla theme with themler and I add content
Then I create a new joomla theme and I have three options:
ADD CONTENT
REPLACE IMPORTED CONTENT
CANCEL
WHAT DO EACH OF THEM MEAN?

THE JOOMLA CMS, THE PHP AND APACHE VERSION ARE OLD, HOW CAN YOU UPDATE?

WHEN I UPDATED THEMLER TO THE LAST VERSION CREATES A BACKUP OF THE OLD VERSION, IS IT NECESSARY OR IT CAN BE REMOVED WITHOUT PROBLEM?
