I upgraded a Magento 184.108.40.206 to 220.127.116.11 and now (three months later) I have some troubles with custom product attributes.
1) One of them is dropdown. I select the option, I save the product and the attribute is well saved. But when I edit the product again, the current attribute option is not selected. When I edit the product, the dropdown field is blank, with no option selected.
2) Another attribute is text field. I replace the old text with a new one, but after I save it, the old text continue to appear, so I guess it doesn't save the attribute at all.
Any idea/sugestion will help. Thanks.
As far as I've tested, this issues affect only the products from the old website. These products were exported from the old website and later imported to the new website (Using Magento's System/ Export and later System/ Import functionality). I can edit other attributes without any issue.
I wasn't able to reproduce these issues when creating new products on the website.
