Hi Bogdan,
i have the same problem. I reinstalled the plugin twice without success.
When i install the plugin on a page-copy in my local test-environment there is no problem with acitvation the child reports plugin.
Hope that helps.
Jens
Hi Bogdan,
thanks for the quick reply.
After uninstalling the database i could install and activate the child reports plugin without error message. Child Report works for me!
