Recently I have revamped a website which is created on a development server. Then after that i started migrating it onto the main server. Initially I got a unicode error while uploading the database on the live server. I googled it and found a solution on stack overflow itself (#1273 – Unknown collation: ‘utf8mb4_unicode_520_ci’). I used the method suggest by sabba and it worked. Later when I Changed the config file and loaded that link. Its giving me a 503 error.. It error is as follows:
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while trying to use an Error Document to handle the request
