Hi Tanya. Usually that means something with your .htaccess file, hosting, DNS, or permalinks isn’t quite right.
Is your multisite network setup in subdomain mode or subdirectory mode?
If it’s in subdomain mode, I would check DNS first. Did you follow the setup instructions? Do you have a wild-card domain? Can you ping the subdomain server address?
If it’s in subdirectory mode, I would double-check your .htaccess file and then your permalinks.
One other thing to try / test – can you create sites normally through the Network Admin > Sites > Add Site, and then get to that site?
If you can’t get to that normally created site either then something is definitely wrong with your DNS / hosting.
If you can post some links that might help too. Let us know if any of those ideas opens up any progress for you.
Thanks!
I was getting the same error. It would show a blank page or page not found.
I changed some settings in my php.ini and it worked. I think it was to do with the max_execution_time it was too short and considering my DB was quite large and my uploads folder was quite bit it was crapping out. Once I changed my php.ini file to the below it worked.
max_execution_time = 5000
Just to note this was on my local machine as most shared hosting will have a cap limit to the max_execution_time in my case it was 90 secs.
