I have similar problem with Twitter, and still have with version 2.6.19
I’m trying to use Facebook and Twitter share buttons in the newsletter by setting following links on them:
https://www.facebook.com/sharer/sharer.php?u=orzola.org
https://twitter.com/intent/tweet?url=https://orzola.org&text=Check%20out%20this%20site
First one is working, but the second one is not:(
I’ve also checked the resulting link:
https://orzola.org/?email_id=40&user_id=7&urlpassed=aHR0cHM6Ly90d2l0dGVyLmNvbS9pbnRlbnQvdHdlZXQ%2FdXJsPWh0dHA6Ly9vcnpvbGEub3JnJnRleHQ9Q2hlY2slMjBvdXQlMjB0aGlzJTIwc2l0ZQ%3D%3D&controller=stats&action=analyse&wysija-page=1&wysijap=subscriptions
Base64 decode says that the urlpassed value is fine:
aHR0cHM6Ly90d2l0dGVyLmNvbS9pbnRlbnQvdHdlZXQ/dXJsPWh0dHA6Ly9vcnpvbGEub3JnJnRleHQ9Q2hlY2slMjBvdXQlMjB0aGlzJTIwc2l0ZQ==
was decoded to
https://twitter.com/intent/tweet?url=https://orzola.org&text=Check%20out%20this%20site
Finally, it was working when I removed the text parameter as well. But I’ve tried a lot of variations, and other request parameters (original_referrer, related) are also causing troubles.
