Upgrade issue

Permalink
We just upgraded our company website from 5.4.1.1 to 5.4.2 and I followed all the installation steps and everything looks great on the front end of our website but in the Dashboard my:

File Manager - has a white screen with the words File Manager nothing else

Users and Groups - blank white screen

Page Types (under Pages and Themes) - blank white screen

Add Functionality - Blank white screen and the name is changes in the left side nav to "Install"

These are my only issues with the install. Any help would be greatly appreciated. I am not interested in reverting back to 5.4.1.1 because our front end is not effected and we are wanting to add the Mobile Template add on which requires 5.4.2.

I had the same issue with the Users and Groups page, an add-on page in the dashboard and eCommerce add-on with a drop box.

All worked perfectly before with 5.4.1.1 but updating to 5.4.2 broke it somehow, updating to 5.4.2.1 did not resolve it either.

I changed the debug level to development and seen this in my source code Fatal error: Call to undefined method AttributeTypeView::field() in /public_html/updates/concrete5.4.2/concrete/models/attribute/types/address/form.php on line 7

After reading this thread http://www.concrete5.org/community/forums/customizing_c5/cannot-add...

I went through and changed all occurrences of $this->field to $this->controller->field in the following files
updates/concrete5.4.2.1/concrete/models/attribute/types/address/form.php updates/concrete5.4.2.1/concrete/models/attribute/types/select/form.php

Everything seems to be working now so hopefully this might help you if you haven't fixed it yet
