If you are manually uploading your flipbooks online via your own FTP client, this problem will occur. Uploading via the built-in 3D Issue uploader will not have this problem.
To resolve the problem, please follow the steps below:
- Open folder and view index.html in text editor
- Find html tag
<img id="cvr" src="files/assets/cover/1.jpg"/>
- Copy src value ie:
files/assets/cover/1.jpg
- Find tag beginning
<meta property="og:image" content=
- Overwrite content value with your domain and issue name eg: <meta property=”og:image” content=”http://www.acme.com/issuename/
- Paste the copied scr value to end of content value eg:
<meta property="og:image" content="http://www.acme.com/issuename/files/assets/cover/1."
After following the above steps, you will need to go to the link below, add your link and click Debug. In the next window, you will need to click on the Scrape Again button.
