So what is happening is that mod_rewrite appears to not be working on the catalog—when i click on an individual item only. This is also happening in the admin.
Everything else is as it should be, but here is what happens in Admin: if i go to Catalog -> Manage Products and select a product to edit, the URL that it points to is correct, but it never gets there. There is a fatal error in app/code/core/Mage/Eav/Model/Entity/Attribute/Abstract.php: Call to a member function setAttribute() on a non-object on line 243. The function is getBackend().
It also appears to be trying to include files from the new version of Magento which are not there.
The same thing happens in the front end when i click on a product, except that the URL’s are not being rewritten at all in that case.
I don’t understant how this could be happening because i have replaced the Mage directory in its entirety with the 6.14 version.
totally lost, been working on this for 24 hours.. would really appreciate any suggestions at all at this point including installing the new version. If i do entirely replace the store, can i still use the data that is already in the db?
thanks in advance to anyone who replies.
