Hello,
1. Check that "System - ARI Extensions" plugin is installed and enabled.
2. Check that "ARI Flip Book" module with ID equals to 80 is enabled and configured properly.
3. Check that "Content - ARI Flip Book" plugin is installed and enabled.
4. If you use a WYSIWYG editor, switch it to plain text mode before inserting plugin code because WYSIWYG editors can add extra HTML code in design mode.
4a. If you see unnecessary HTML code, use the solution from
this post.
PS: If nothing helps, could you provide temporary access to your J! backend by
email so we could investigate the issue?
Regards,
ARI Soft
