import/export,products not showing in the admin

Hello,
I have an problem using the import/export tool

My problem is that items that I add in the data base, appear in the store front, but not on the admin pages. Neither categories, nor products do appear in the admin, although they appear in the store front...

Iám using Opencart 1.5.6.4

Thank you for the help.

Greats Ben

Hi there,

I am having the exact same problem. No one here to help, please ? Have you solved it ?

Perhaps this might be your problem?
