hi, I updated to the most recent version from a very old version.
I run different metas for various products, but I have some fields which are the same for various products. When I updated on my staging website to test everything I can see this error message: Some of your fields has duplicated datanames, please fix it
since you updated from very old version, you need to recheck your field’s settings again and make sure each field has unique and proper lowercase datanames. Once they are set this will all ok.
