Tooltip

believerinsight: I have had trouble with this as well, even in the last version. The source of the problem has been the use of this apostrophe character ‘ in the excerpt.

The solution, until fixed, is to replace any instance of ‘ in an excerpt with an alternative single quote character, such as ’.

Please let us know if this is the cause of your problem as well. If not, check for other special characters in your excerpt and try to remove them and test again to determine the source of the problem.

There’s no known issue with apostrophes in excerpt (generally: tooltip content) in version 2 (it now uses WP Core esc_attr function to avoid such issues) .
However, not appearing tooltip could be caused by cache (either page/minify/js cache on server side or browser cache) since the way the tooltip is invoked has been changed in new version.
Please try to refresh browser cache and server cache (if you use any kind of plugins like W3 Total Cache) and make sure that tooltip.js file loaded into your browser contains this snippet:
$(document).ready(function() {$('[data-tooltip]').glossaryTooltip()});

If the problem still exists, please provide a link to a site where we can check your problem.
