Hello

I have an installation on my top domain.
I have recently installed a second version on /testSB/ to prepare the future installation on my top domain.
when trying to access www.subicicleta.com/testSB/, I got the custom error page of the top domain. error page not found

Top domain: www.subicicleta.com
test version: www.subicicleta.com/testSB

Can anyone help me with this matter?

Thank you!!
