I updated the plugin, and it’s partially solved.
Now I can see more columns but it makes a stairs effect as you can see here:
http://www.juditpolo.com/test1/
What can I do to solve this?
You are right, I don’t know why there where errors, I deleted that URL.
Try this now: http://www.juditpolo.com/test1/
Still only one column but no errors in the URL.
Still not working..
Here’s the URL: http://www.juditpolo.com/test/
