My membership has lapsed and I don't see any official way to submit a bug report, so I hope you don't mind I do it here. I spent a couple hours on this today and I'd like to save others some pain.

I'm running the latest version 5.5.11 (Reboot theme) and I noticed in Chrome and Edge the Add Topic and Add Reply buttons weren't working (nothing would happen when clicking them). When I looked for JavaScript errors I saw this:

`selector` option must be specified when initializing tooltip on the window.document object!

I traced the source to the call to bootstrap's tooltip function in this code:

if (sp_platform_vars.device == 'desktop' && sp_platform_vars.tooltips == true) {
 jspf(document).tooltip( {
  tooltipClass: "ttip",
  position: {
   my: "left+20 top",
   at: "left bottom+10"
  },
 track: false,
 content: function() {
  var element = jspf(this);
  if (element.prop("nodeName") == "IFRAME") {
   return '';
  } else {
   return element.attr( "title" );
  }
 }
 });
 }

The workaround to fix this was to set the tooltips variable to false in spFunctions.php:

if (!defined('SP_TOOLTIPS')) define('SP_TOOLTIPS', false);

If you'd like additional help investigating this, let me know.

Cheers,
