I wasn’t using a plugin to edit the metadata, I couldn’t get in to edit through the product pages in WooCommerce or under the Media Library tab. If I clicked the edit button, I would get a new page that said something like “Unable to access this page”, no matter which image I clicked.
I am also using a plugin called “Photo Video Gallery Master” but not for editing the photos. I set up my additional images in the Galleries and paste the shortcode into my product description. That is it for anything to do with media, Just WC, the Media Library and this plugin – but I do not edit files using this plugin.
I also had issues on uploading images. Some of them would not get thumbnails. I would try to regenerate thumbnails, some would work – most would not. When I switched back to Twentyseventeen theme, I could edit the images with no problem, however I still could not get the thumbnails to work.
On a separate note, I created a brand new install of WP and WC on a new domain… I uploaded this the gallery plugin and a bunch of images to play with along with the twentyseventeen theme. They loaded perfectly. It took me a while to figure all of this out, but I think its the Customizr theme that created the issue. It sort of messed up my media library on the first install.
I am a novice to WP… I liked your theme and was getting used to it but this issue made me crazy!
Hope this Helps
