Internal Server Error 500 - Entering Products

I have a new installation of 1.3.9.

When I try to add products I get an Internal Server Error 500

I have checked the server log and found this;

[18-Nov-2010 07:32:34] PHP Fatal error: Call to a member function get_template_part() on a non-object in /home/xxxxxx/public_html/index.php on line 29

Any ideas what this is? I checked the line in index.php and it is:

$directory_array = $template->get_template_part($code_page_directory, '/^header_php/');

Any ideas, my knowledge of PHP is only very basic.

Thanks in advance. :-)

thanks kobra

I have already tried the Tutorial/FAQ, which is why I found and posted the server error message...

Fatal error: Call to a member function get_template_part() on a non-object in /home/xxxxxxx/public_html/index.php on line 29

I need some help interpreting what this means as the front end will also not work now and has this message showing when you go to my URL https://www.equestrienne.com.au

OK...it looks like I am getting file corruption through the FTP...Dreamweaver is the culprit, I have gone back to using Filezilla!

:-)

Dreamweaver is the culprit,
IMO Never use it for any php editing nor as a FTP client
It is a html page editor only - no matter what they say
