Content disapears when viewed on mobile

Hi Tonk..
This is a well known issue, I see you’re using customizr 3.1.13 and this should not happen. The reason why it’s happening to you is that, probably, you have copied an old customizr version index.php in your child-theme.
Solutions:
1) Remove all templates file you don’t need from the child-theme
2) replace in all your needed template files from the child-theme, this line:

<div class="row">

with this line:

<div class="<?php echo tc__f( 'tc_column_content_wrapper_classes' , 'row column-content-wrapper' ) ?>">

which you can find after the line:

<div class="container" role="main">

Thank You!!
After I replaced the index.php file with a recent one the problem was solved!

Could you mark this topic as resolved?
Anyway why you have an index.php in your child theme?
