Problems with installation plugins and template

Hello, I bought and I liked the extension is complete and will serve my needs very well, but I'm having a little trouble and doubt.
to install any plugin I get the following error: "PHP Warning: constant () [<a href='function.constant'> function.constant </ a>]: Could not find constant JPATH_ in E: \ home \ suavendaim \ Web \ libraries \ joomla \ installer \ adapters \ module.php on line 117
PHP Warning: constant () [<a href='function.constant'> function.constant </ a>]: Could not find constant JPATH_ in E: \ home \ suavendaim \ Web \ libraries \ joomla \ installer \ adapters \ module.php on line 119 "
It would be a possible help?
And in terms of doubt as to the template, much like the one used in live demo ( osproperty.ext4joomla.com/ ) where could something similar?
thank you

Hi,
The problem you have is the normal warning of PHP. To solve this issue, please add error_reporting(0) in the top of the index.php in root folder of Joomla. After <?php
The template of the demo is JA Travel. You can contact me with Skype name : thucdam84 to get more support from me.
Thank

Hello! Unfortunately it did not work the tip, insert the information in index.php, but the error persists (in time) you added in my skype nick is drako.sp

The theme is very expensive ... wanted something cheap or zero cost.

error_reporting(0) is not a good solution sir.

It may temporarily useful to hide the errors but the propert method is to find the bug and solve it.

in future this small hidden warning have chances to become larger one and left unnotice.

whats the error about by the way?

I have checked on his site. he uploaded the Joomla from localhost, so it has E: \ home \ suavendaim ....
We have fixed that issue.
