How do I fix the appearance of my website link on Facebook?

Check your site with the Facebook debugger

How are you posting the link to your FB page?

Hi Steve, I just copy and paste the link into a facebook post. For example I’ll post something like this:

Join us on the Ultimate Beer Tour in 2018! Space is limited – sign up today! https://www.eatanddrinklikeaeuropean.com/tours/beer-tour/

Then it automatically puts up a picture and that weird text underneath it.
If you follow this link https://www.facebook.com/EatandDrinkLikeaEuropeanTours you can see what it looks like.

This may be Divi issue if you get those et_ shortcodes.

Commercial products are not supported in these forums. You are their customer; I am sure they will have no problem supporting you there.

Thank you – I will contact them!

…and puts some gibberish underneath

Ensure that you have fill up the excerpt box in your individual page settings at the bottom.

That’s the only tip I can give. You have to ask Divi support community for the rest. Good luck.
