When I have shared my newsletter on FB, Twitter and also via a button on my website it is returning a blank page. Also all my campaigns now have an icon with a diagonal line through the preview ‘eye’. They have sent to my subscribers without any problems. Any ideas to solve this very welcome
It sounds like your option to have view on the web links for your campaigns was turned off. If you go into your addons and look at the one called Campaign Tweaks, there's an option there to include a view on the web link in your emails. If that's turned off, then your campaign is considered private so it can't be shared on social media. I've included some screenshots to help you find the setting.
