yes exactly first of all you rename the attitude folder pro from your ftp and then only install it. Because on the same directory the same folder cannot be used.
Thank you
hi
first of all download the zip theme and then rename it.
Then go to dashboard-> appearance-> themes-> add new
and upload that zip theme. The same two theme will be shown there and preview the theme. You can find the new one with its latest version after preview.
Then active the latest version.
The next way is from ftp
go to ftp of your site
inside wp-content->themes
upload the new version of the theme and before doing that first rename the older version of theme.
Thank you
