I'm developing a website that requires Events Management with Google maps support. As I didn't find anything that could fill my requirements in this site, I was forced to use the "Events Manager" plugin from other site. Nevertheless, when I add a Facebook Like Button (http://sacv.web44.net/eventsview/event/la-arrolladora-banda-el-limon/, this is just a test site) to the single event page, and click on the like link, and after being confirmed, when I check the link on my Facebook profile page the link to the event page, this is incorrect (http://sacv.web44.net/eventsview), where the last part of the url is missing. However, if I copy the link directly in my Facebook wall, it takes the right url and the right info.
I also used the default permalink structure instead, and the same problem happened.
I check the source code of the plugin and they use is own database table to save the data, and hook some functions to template_redirect to show the info of the single event depending on the url.
My question is, what might cause Facebook not to take the full URL with the Like Button?
