The webhost which looks after a magento instance messed up all of the file ownerships and permissions. They have now stated they have sorted it out and we can now FTP in and upload files. The issue we have now though is that when a customer updates the quantity in the cart it doesnt work.
Looking at other posts it would seems to lead to the form_key field however I can see this field in the source code eg:
<form action="https://www.example.co.uk/checkout/cart/updatePost/" method="post">
<input name="form_key" type="hidden" value="BRTMA77qNzgbkgDT" />
So I dont believe its that.
I have tried to clear all magento and browser cache but no luck. Has anyone got any suggestions.
Update I think the issue is with _validateFormKey function in /app/code/core/Mage/Core/Controller/Varien/Action.php
If I dump out the values
zend_debug::dump($_POST);
zend_debug::dump($this->getRequest()->getParam('form_key', null));
zend_debug::dump(Mage::getSingleton('core/session')->getFormKey());
I get
array(0) {
}
NULL
string(16) "BRTMA77qNzgbkgDT"
So it looks to me the POST is being cleared but not sure why
