ffs-three-one Max Tab Limit???

Hi,

Firstly, I got to say great plugin. It does what it needs to do. But my reason for this post is to find out if there is a limited number of tabs allowed?

What happened was, I added quite a number of tabs, hit the update button and suddenly the page I was working on disappeared on the live site.

At first, I thought I placed the codes wrongly, but after a few test (remove and adding), I realised that the moment I add another line of ffs-three-one my page vanishes.

Any idea why this happened?
