Hi,
We recently had to shut off all our plugins as we migrated to a new server and when we turned on the 3D Flipbook plugin it produced the error below.
The plugin generated 40 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
Please advise.

Could you write here these 40 characters? What is it?
This is the error message.

Where would I find the 40 characters?
Here is what I found online: https://wordpress.stackexchange.com/questions/16547/wordpress-plugin-development-headers-already-sent-message
So at the moment the 3D Flipbook plugin is breaking my theme header but I have it on a staging server now and disabled on the live site.
If you have a private link I can send you the site URL.
