Magento configswatches Call to a member function toOptionArray() on a non-object

Question

I am using Magento 1.9.1.0 when I go to admin >catalog > configurable swatches in admin

I get the error below:

Fatal error: Call to a member function toOptionArray() on a non-object in app\code\core\Mage\Adminhtml\Block\System\Config\Form.php on line 463

My magento version was updated from 1.9 to 1.9.1.0

I could not figure out how to fix it, based on some online research when I comment below text from file "app/code/core/Mage/ConfigurableSwatches/etc/system.xml"

it works fine

commented text :

Answer 1

That means, the source model for these form fields could not be loaded. Check if the following files are present and readable:

• app/code/core/Mage/ConfigurableSwatches/Model/System/Config/Source/Catalog/Product/Configattribute.php
• app/code/core/Mage/ConfigurableSwatches/Model/System/Config/Source/Catalog/Product/Configattribute/Select.php

Hate the 50 points to comment. Anyway tx to fschmengler. Looked and said file was .ph and not .php Why? Haven't a clue as the file isn't that way from Magento. I have re-downloaded and uploaded new a few times. Each time it had this error. Now gone. yeah

Just a bit more on MY finding. Did a search and found about 45-50 files that end in .ph and not .php. Checked the source file from Magento and it is .php. Said files have been both FTP directly and also unzipped on the server itself. Looking into WHY/How they get changed to .ph. The ONYL other thing I found online about .ph is from 2007 for Zen-Cart. Oddly persons server also had webshell...
