thanks for your support.
I’m in a shared, and everything ran smoothly (some minor problems apartdue the 2.7 install was instead a 2.6.5 )
honestly I didn’t check apache error log, this apart I’ve carefully followed the install/upgrade guide lines.
‘My’ site is then running the ‘old’ RC1 at the present,and it’s located at zerorelativo org
the php info if needed is on /info.php
I’ll stress out that the ‘disappearing’ begin just with the Core -alone- uploading/install
