I think I resolved the issue.
I uninstalled Lavender and reinstall it. Seems to be only one instance now
Right now it displays 4 columns and the fifth is on the line under - Where do we edit that?
This is less a bug than a feature request for the theme. You can develop your own theme to display five columns or make changes to Lavender to do so by editing the home.tpl file.
@Tanner Sorry, you're right. Still I can't find the passage to edit it. I can only define the column size, if I make them smaller, they still won't appear on a single line.
@Tanner nope, nevermind. just had to edit col-md-3 into col-md-2
@Giorgio-Chiodi can you tell me where to define column size ? I want to it displays 3 columns every line.thank you.
As replied here https://community.nodebb.org/topic/2217/how-can-i-display-3-columns-in-the-lavender-homepage/2
Just change col-md-4 by col-md-2 And on the first category you need to add col-md-offset-1 aswell.
This method will only work with second solution. Or you can add col-md-2 col-md-offset-1 aswell on the first item in ACP after doing first solution.
