Hi,
I’m having the same issue and I’m using the latest version (just installed 3.1.16) and Chrome.
(WooCommerce, WPML installed) “SubstituteMaxLineLength 10M” is added to .htaccess file.
– I’m able to see your template library
– I’m able to select one (Organic template) and add our logo
– After I select a font on the next page, click the button
then, I just see a light gray colored blank page.
Thank you,
Eri
