Fatal error: Cannot access private property Document::$title

[RESOLVED - see post from Qphoria in this thread]

Upgraded from 1.4.9.4 to 1.5.1.3

I can't post the link at this time, it contains the cpanel username.

After following the step by step instructions with the Beta3 script, I followed the upgrade.txt file that comes with 1.5.1.3. I obviously missed something in the process, because I'm receiving the following error when, in the admin, I navigate to Extensions > Cart > Edit
Any ideas?

That is an old 1.4x module that doesnt exist for 1.5 , so you should probably delete it.

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

as those are no longer needed

Hi there,

I've got the same problem, described by amelie. The difference in my case is that I'm running Open Cart 1.5.6 and these files that Qphoria has said to be deleted, they don't exist in my version of OC. I tried to upload a payment module and got this error. I don't know what I'm doing wrong. If anyone can help me, I'll be truly grateful. Thanks in advance and Happy Holidays!!!
