White Screen after moving server

Hi

I've moved a dev site from an old server to a new server and I am getting a white screen on the front-end. The back-end is working and here are the diagnostics;

Perch Runway: 3.0.10, PHP: 5.6.38, MySQL: mysqlnd 5.0.11-dev - 20120503 - $Id: 76b08b24596e12d4553bd41fc93cccd5bac2fe7a $, with PDO

I've looked through the help doc about white screens and looking at my error log on the server. Its saying this;

[core:crit] [pid 28509] (13)Permission denied: [client 5.8.10.202:45470] AH00529: /home/stottoco/public_html/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable and that '/home/stottoco/public_html/' is executable

The htaccess is readable and /home/stottoco/public_html/ permission is currently 750

This is a new dedicated server the client has got, so maybe it needs something adding/allowing on the server? I thought I would check here in-case I needed to do something this end?
