 * WordPress 3.8.1 running Mantra theme.
 * I enabled RSS and started receiving 6 of these messages at the top of the main
   MF Gig Calendar Page: _websitename.com_**/wp-admin/admin.php?page=mf_gig_calendar**
 * > Warning: assert() [function.assert]: Assertion failed in /home/USERNAME/public_html/
   > wp-content/plugins/mf-gig-calendar/mf_gig_calendar.php on line 1114
 * I unchecked RSS and am still receiving 3 of them.
 * Line 1114 is:
 * > .gallery-columns-9 .gallery-item:nth-of-type(9n) {
 * You can see what is above and below line 1114 here:
 * > .gallery-columns-1 .gallery-item:nth-of-type(1n),
   >  .gallery-columns-2 .gallery-
   > item:nth-of-type(2n), .gallery-columns-3 .gallery-item:nth-of-type(3n), .gallery-
   > columns-4 .gallery-item:nth-of-type(4n), .gallery-columns-5 .gallery-item:nth-
   > of-type(5n), .gallery-columns-6 .gallery-item:nth-of-type(6n), .gallery-columns-
   > 7 .gallery-item:nth-of-type(7n), .gallery-columns-8 .gallery-item:nth-of-type(
   > 8n), .gallery-columns-9 .gallery-item:nth-of-type(9n) { margin-right: 0; }
   > .gallery-caption {
 * Any ideas?

 * Hey there. Sorry to go missing so long.
 * I’m not able to duplicate this on any of my installations. Not saying it’s not
   my problem, just I’m not sure how to test/fix it here!
 * That assert() reference is used as part of what truncates the text in the event
   list in the admin area. It’s a block of code I reused from a reference online.
   It’s really in there for testing and should only give an error if the html in
   the description or location field is not properly nested – so I’m guessing that’s
   why you’re getting the errors and I’m not.
 * I actually just commented line 1114 out of my plugin (mf_gig_calendar.php) and
   it works fine.
 * Like so:
 *     ```
       // assert($openingTag == $tagName); // check that tags are properly nested.
       ```
   
 * Feel free to do the same and see what happens. It won’t hurt your data – at worst
   something may look funny in the admin area’s event list if there really is something
   funny with your html. But I guess errors look funny too, don’t they!
 * I’m reworking a lot of this in the next version of the plugin.
