Upgrading Homepage Problem

Hello,

I have just upgraded my opencart from 1.4.9.4 to 1.5.1.3 today.

And I followed the instructions "Beta3-14x-to-15x-upgrade-step-by-step" carefully.

Admin panel is Ok but I can not change system/settings/store template and layout to "default" , I change but when I check again template turns "mytheme" and layout turns to "checkout" .

Homepage is NOT OK , I can not open some extensions modules like manufacturers (Fatal error: Cannot access private property Document::$title in /home/content/61/7784261/html/admin/controller/module/manufacturer.php on line 8 )

There are some failures on the homepage.

What can I do , please help !!!
Thanks

Step 1: Type "Fatal error: Cannot access private property Document::$title" into the Opencart search facility

Step 2: Previous postings suggest this is referring to an old v1.4.x module (manufacturers) that no longer exists in v1.5.x

Step 3: Follow these wise words:

Qphoria wrote:delete the following files:
admin/controller/module/cart.php
admin/controller/module/manufacturer.php

as those are no longer needed

Thank you very much ,

For now I restored my opencart to 1.4.9.4 Since I could not manage to upgrade properly but I am planing to try again , if I get the same errors I will do as you said.
