Only Display one column on all the pages

-- url of the page with the problem -- : www.patisserie-hoffmann.lu

Hello,
since the last update I made about one hour ago, all the products are displayed in only one column instead of 3. (category and product display)

I changed 3 columns in the main configuration but there is no change. Before the update I had a second tab in the main menu options, but this tab with all the display configuration disappears.

Can you please check this. Attention there are a lot of changements in the template (most from your side)

Hello,
I am a little bit confused.

What I had before the update: Categeroy view (two columns with img and title) / Product View (tree columns with img and title)

- When I change the frontent css to "old" in the configuration/view, then I have in Category view = 1 column, in product view 3 columns.
- When I delete the .hikashop_subcategories... in line 42 of the old frontend css (because the new default frontend css do not has this line) then I have in Category view = 2 columns, in product view 1 column.

Where can I change the number of the rows/columns for EACH category of products? I can not find it in the configuration documentation, because on the earlier version of hikashop it was very simple. There I changed the number of colums/rows, products that are in the same category etc in the tab of the menu configuration.

Thanks for your help

Hello,

As I wrote on the last reply:
- The frontend_custom.css do not have this line 42?
- Only the old frontend_custom.css contain this code on line 46. When I remove it then I have in Category view = 2 columns, in product view 1 column. This is still not what I had before the update (Categeroy view (two columns with img and title) / Product View (tree columns with img and title)

The other problem with the tab view is ok. Thanks

Thanks for your help
