Hello Dark, thanks a lot for your help. I tried to implement it but it didn't work (I'm not a coder so I most probably made a mistake). I added the code in my template, since this code has to go in ALL of my pages. This is what I added to my page's code:
<!-- SPOT.IM (MESSAGES) -->
// build the Link (URL) like:
$sPageUrl = WB_URL.PAGES_DIRECTORY.$GLOBALS['wb']->page['link'].PAGE_EXTENSION;
// the ID like:
$sPageId = 'P'.(string) $GLOBALS['wb']->page['page_id'];
// Now you have the two important vars and can build the needed API calls for SPOT.IM
<script async src="https://launcher.spot.im/spot/mySpotImNumber"
<!-- END SPOT.IM (MESSAGES) -->
I am assuming that the Page's URL is stored in $sPageUrl and the page's ID is stored in sPageId, is that correct? Also, please note that I added ?> because I was getting an error without it.
