We have a Social Share Buttons widget installed on a Squarespace site.
There is a recurring issue with the Facebook share button where the “Create post” window doesn’t load when users are trying to share the post to a FB page they manage (see screenshot). But it seems to work fine if they are using a personal FB profile.
Has anyone else encountered this before?
Here’s an example of a page on our blog with the Social Share Buttons:
Hi there, @sia_soroptim 
I’ve checked your website and tried to share your website on my own Facebook page and everything worked fine. However, when trying to share it on the page where I am just a moderator, the website can’t be shared.
I guess you should be the owner or admin of the page to use the Share option, but I’ll double-check it with the devs and get back to you tomorrow 
Hi there, @sia_soroptim
Yep, devs confirmed that you need to be an owner or admin of the page to share links. This restriction comes from Facebook and, unfortunately, there’s nothing can be done with it.
Please let me know if this explains things or if you have any questions left
