Changes to content menu/mudule not saved

Hi,

Just upgraded to Business version and successfully imported products from Virtuemart.
Now trying to create a category menu item and a category module listing.
However, every setting that I change is set back after saving.
For instance: I try to set the amount of category columns to 3, but after saving the field is empty.
This also happens with other settings...

Any ideas?

Thanks in advance

Hello,
Can you :
- Activate the Joomla debug mode ("Administration->Global configuration->System->Debug System/Language")
- Set the "error reporting" option of the Joomla configuration to "maximum"
- Test it again so that you can see if it display an error message which will help you to understand from what your issue is coming.

Hi Mohamed,

Thanks for your reply!

I did as you said and get the following error:
In the column amount field: <br /><b>Notice</b>: Undefined index: columns in <b>/home/rkas/domains/polydeco.net/public_html/administrator/components/com_hikashop/views/menus/tmpl/form.php</b> on line <b>107</b><br />

Now no categories are showed at all....
