Before you start upgrading, take backup of your site including database and files.
If you have site with non english language, you need to convert database to UTF-8 before you upgrade vshare. If you do not do this, there are chances of some charactor get changed.
We recommend "Approach 3" described at
http://www.mysqlperformanceblog.com/2009/03/17/converting-character-sets/
If you don't know how to do this, contact [email protected]
If you skip this step, site will work, but there can be chances of some characters displayed wrongly.
You can delete (or move to a temporary folder) all folders and files other than following
chimg flvideo photo thumb video include/config.php
I suggest you to move the files and folders to a temporary folder, so you can refer them if needed. Most FTP software allow you to move files and folders.
Download vshare2.7.zip from
http://buyscripts.in/download/vshare2.7.zip
Extract and delete include/config.php from extracted files.
Now upload everything to your server, make sure you don't overwrite include/config.php file in server.
Make following folders writable by web server.
chmod 777 cache chmod 777 include/htmlpurifier/HTMLPurifier/DefinitionCache/Serializer/HTML
After you uploaded new files, you need to run upgrade.php to upgrade database.

After upgrade finished, delete the install folder.
By default progress bar is disabled, you need to enable as per instructions provided at Enable upload progress bar
