WordPress 7.0 beta 1 , please help i really want to test this baby!

Hello ,

i was so excited to test wp 7.0 beta but unfortunately i have problems installing it ( i have installed wp before successfully so i dont know what might be wrong this time)

I am getting this error

Parse error: syntax error, unexpected $end in /home/*******/public_html/beta/wp-includes/post.php on line 648

when clicking to install

Does anyone knows what can possibly be causing this?

I have everything set correctly or at least i believe so, there is only one thing i am not sure of: I uploaded the wordpress folder after renaming it but didn’t create a subdomain, could this be the problem? ( i thought i didn’t need a subdomain and that the wordpress directory will do, but i might be wrong)
