Parse error: syntax error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in *plugins/system/autotweet.php on line 26

I got this error message when using the Plugin Autotweet on a new installation of Joomla! 1.5

Parse error: syntax error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in *plugins/system/autotweet.php on line 26

The problem had occured because I had not set up my webspace to be using PHP 5.

The Solution:

open up the file htaccess.txt in your editor.

add the following line to the top

SetEnv DEFAULT_PHP_VERSION 5

now save as .htaccess

and upload.

THATS IT !!!!

hope this works for you.
