Unable to create Cost Centers

Hi everybody!!

I’ve made a lot of progress installing my own server instance of ERPNext. At this time, I cannot config my Cost Centers, as you can see in the below picture:

Somebody know how to fix it?

Thanks a lot!!

What errors if any are you encountering ?

Could not find parent Cost Center:

I’ve input the Main Cost Center at the tabCost Center… Now it’s working!

EDIT: Better, I’ve installed another instance, edited some cost centers, opened the database, exported as CSV the results, and import at the broken instance… voilá!!
