Since I updated to Joomla version 3.4.8 crashes when I go in the Template and not driving me. I installed the version of the template of September 2015. I read on your site that is compatible up to 3.4.4. What can I do?

@Nerio Zanzini: You also need update Helix Framework to latest version after update Joomla to v3.4.8.
You can download latest version of Helix II Framework here: joomla.vinagecko.net/l/Helix2-Plugins-Package.zip

I'm having a problem with the article accordion on the front end...
The top article shows perfectly. The articles below show the headline and the arrow to expand the accordion, however, when you try to expand it to preview another aticle... it all disappears and shows a blank area. When clicking on the arrow again to contract the accordion, its back to normal.

Can you please have a look to see what I mean - here

Normal display


After expanding accordion to preview next article

@Casey01: It seem like you are forget to close HTML tag in description of article: 1st Place 2016 World Salsa Championships (HK)
Please check your article content and insert close HTML tag.

Sorry for my ignorance... not sure where to insert the close HTML tag (you mean this kind of tag? </html>)?
Does it go in the source code of the article? Or in the title of the article?
I tried to compare my article's html source code with the html source code of the articles from the template... and I don't see any HTML tags...?

Please disregard my previous message. I figured it out!
It was <a href = tag that was not supposed to be there! I removed it... and its all good now!
