Question forum creates problem for pull down menu sub-categories

This issue only happens on the forum page (no other pages on website):
meetyourpsychic.com/forum/index (no issues on other pages such as meetyourpsychic.com/ )

When you mouse over the top "mainmenu" categories (such as "Readings") the sub-items have a 20px gap which causes navigation difficulties.

Also, how do I remove the "Rules" tab?

Thank you

Try by adding the following lines to the end of your Joomla site template CSS:
For Rules tab matter, this is answered in the FAQs tab at the top of this page; see Kunena menu issues sub-heading How do I edit, hide, disable or translate menu items in K 1.6 (e.g. rules, help, search)?

Thanks, I found how to edit the menu options (Joomla Admin/Menus/kunenamenu)

However the code you suggested did not fix the menu options. I'd be happy to give you ftp/super admin access if you want to take a crack at it.

The problem is not caused by Kunena. Thank you for explaining what you mean by "pull-down menu". Your site template (../templates/rt_nebulae_j15/css/template.css) has the following rule (at around line 149): Comment-out the z-index rule.

I deleted this line but it did not help:
{position: relative;z-index: 100;border-radius: 6px;}

I'm not sure how to comment out but am more confident about deleting a line

Thank you for looking!

That last change didn't help. I was wrong. I've spent the past hour looking at this and the only thing that I can say with certainty is that there's some CSS conflict somewhere between your menu system and the Kunena component display and I can't tell what's causing it. I don't think I've ever had to admit to defeat but, on this occasion, you got me. I think you will probably have to refer this matter to Rockettheme. Maybe someone else (who hasn't been awake since 01:30 this morning) might be able to cast fresher eyes on the problem. Sorry, but on this occasion, I can't help you.
