Hi,
Thanks for using our plugins. I can try to help out on this customization.
I tried out that coding and got it to work for me.
I did notice that in this function:
build_fb_link
The link to Facebook did not include events in the url.
So instead of this:
http://facebook.com/”.$eventID.”‘
I changed it to this
http://facebook.com/events/”.$eventID.”‘
Let me know what issues you are having and I can try to help out, but there is not much we can do to support a custom coding provided by other customers.
Thanks
