Hi,
I know thta this case ist already explained in the knowledge base. So I tried all options described:
changing the theme (enfold > twenty fourteen)
disabling plugins (not woocommerce)
checking error log (is empty)
trying different compatibility settings
But nothing helped to solve the problem. As far as I remember the functionality was OK, before updating to a new version.
Now that you have all access data I hope you can detect the problem.
Thanks in advance
