RE: Can not share event from events portal on Linkedin
[quote user="Nya"]
Hi,
I found that the URL in your screenshot has been customized. The original URL ends with "?id=Event_xxxxx".
If the URL has been customized, copy this URL directly to a new page to open it, it will show Page Not Found.

It also reports a 404 error in Post Inspector.

You need to click on the icon to the right of the URL to open it and the new page will open with a redirected URL.

Copy this link to Post Inspector and it will work fine.
If this helped you, I'd appreciate it if you'd mark this as a Verified Answer, which may in turn help others as well.
Best Regards,
Nya

yes. The url is customized. And when a copy the url it looks likes the page is opened right.
But when I open the developer tools (F12). I see a error message:

I don't know why I get this message but I think I must solve this first.
