问题
I had updated my xcart site from 4.X.X version to 4.7.6 version. All works fine but the look and feel of my site changed completely. I was using 2-column skin in older version and I want exactly same look as that in old version, but after upgradation look of my site changes completely.
What I had tried : To recover that I copy the same 2-column skin of older version in my new version, and it goes well. But now the problem is Iam not able to display categories.
What I had tried : To recover the category issue I copied the categories.tpl file code of "common_files" skin in my custom skin in category.tpl file under customer folder.
Still facing this problem Now categories are showing but if I click on any category it open up with a blank page
回答1:
1)Check the log files in your X-Cart installation in the var/log folder
2)Compare these tpls with your ones
skin/common_files/customer/main/subcategories_t.tpl skin/common_files/customer/main/subcategories_list.tpl skin/common_files/customer/main/subcategories.tpl
3)Try to enable/disable this option 'Display subcategories list in multiple columns' on the page http://YOUR_SHOP/admin/configuration.php?option=Appearance#tr_subcategories_per_row
