Getting 504 timeout error importing xml files for zero theme. I checked the article posted by gracethemes on today about WP 504 errors but nothing remedied the situation. This is only happening with your themes
I wanted to update in cases anyone else has this issue and hopefully to save you a lot of time. My hosting company had my IP address on a “greylist” , meaning they were blocking my IP. It was probably because I am running a VPN. Hope that saves everyone some time.
