Ive installed OST on a local machine with xampp and everything worked fine. I've used IMAP to poll e-mail from a google account and it worked flawless. This was just a regular windows machine with no ssl etc installed.
I then tried to move it to an server with php7 and didn't work.
I've now tried on a different server and when I try to add an account it spins "loading" and then crashes with google chrome saying:
ERR_EMPTY_RESPONSE
I've also tried to manually add an account by typing in the database but it doesn't fetch any mail..
Attached you see my configuration
