Fatal error: main() Failed opening required '' in tpl_index_default.php

[sprintstar]

I have just suddenly started getting this error message (amongst others) on my site (www.t3tuning.co.uk).:

Fatal error: main() [function.require]: Failed opening required '' (include_path='.:/usr/lib/php') in /home/t3tuning/public_html/shop/includes/templates/template_default/templates/tpl_index_default.php on line 42

Its running v1.2.5 of zencart, and is a mature site having been up for a while. I haven't changed any files recently, so it must be a change on the server of some sort.

The line in question is:

<td class="plainBox"><?php require($define_main_page); ?><br /></td>

..and it looks like "$define_main_page" is not defined on that page. It must be defined somewhere, but what could have changed on the server that could have broken this mechanism?

I have searched the forums, and people have had some similar problems (like http://www.zen-cart.com/forum/showthread.php?t=47585), but no definate solutions. I am getting no help from my hosting co, and am getting desparate!

Thanks, Chris

Anyone know the answer??

Your permissions on your /includes/languages/english/html_includes files are too low, causing them to not be readable, and thus the error.

I don't have an html_includes directory in /includes/languages/. Should there be one in my version of zencart? I have lowered all permissions on everything in the /includes/languages/ folder, with no change..

Well, your code is making reference to "define pages". Those are stored in the /includes/languages/english/html_includes folder.

Ah well I have an html_includes folder in /includes/languages/english/, but I have set the permissions on everything in the languages folder to 766, with no change. Where does $define_main_page get assigned a value, and what could have suddenly changed on my server to stop this working?
