3D FlipBook - Was working great, now...some pages are blank, or spinning wheel

Hi, did you solve the issue?

NO...please help!!

we need a link to any page with this issue.

All the information is in my first post above, including the link! here https://www.colettehosmer.com/press-2/ If you scroll down to the thumbnail gallery and click the first item....

there is error in debugging console:

Access to fetch at 'https://colettehosmer.com/wp-content/uploads/2021/02/4.2018-The-Magazine.pdf' from origin 'https://www.colettehosmer.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

you need to allow CORS for pdfs. If you use apache web server - insert in .htaccess (file in the root folder of your site):

# CORS for PDFs
<IfModule mod_headers.c>
<Files ~ ".*\.pdf$">
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Methods "GET"
Header add Access-Control-Allow-Headers: "Range"
Header add Access-Control-Expose-Headers: "Accept-Ranges, Content-Encoding, Content-Length, Content-Range"
</Files>
</IfModule>

Thanks for that. It appears to have fixed the spinning wheel/timeout issue, but some are still loading blank pages. If you go to https://www.colettehosmer.com/press-2/ Scroll down to where you see the multiple rows of thumbnails. On the top row, from left to right, #1 is good, #2 is good, #3 is good, #4 and #5 are blank pages. On the second row, #1 and #2 are blank pages. All of these worked previously. Thanks for getting back with me.

they have 0 pages in JS data, probably they were saved with an error or before the book processing was finished. Go to those books editor, wait when book processing is finished and click update.

OK, it looks like the ones that work OK are PDF's and the ones that show blank pages, the 3Dbooks are image pages. I've gone to a book that's comprised of image files and checked each image file in the book and they show up OK as links in the 3dbook and also when I open the links directly in a browser, then I've hit 'Update', but it doesn't work. So there's something about books using images as pages that's changed. Again, this website was built months ago and fully tested and everything worked fine.

So on the top row of thumbnails on this page https://www.colettehosmer.com/press-2/ #5 from left to right shows blank pages. The books pages are made from image files, not PDFs. The image files stored in the book are here:

The images appear OK when fetched directly in the browser but not in the 3Dbook Any ideas?
