Export PDF with images

I have two problems when I export my page it opens up as a blank Blob: page
Why is this happening and how do we export images in PDFThanks

Enable debug mode (Tools → Advanced Settings → Debug) and press F12 → Network to check the error response.

I have checked there are no errors, this only happens when I export css, When I export HTML the images show.
Also the captions do not export.All this done in advanced settings

Did you get your exported pdf document? If no, there should be an error message. As explained, you should enable debug and press F12 → Network to check the network response.If you are a registered user, you should send your project file/database to the support email for quicker resolution.

Also the captions do not export

Enable Tools → Advanced Settings → Export field captions
