Config for serving website on nginx server via sub url

Most likely reason for the php files being downloaded because the php handling location block in nested under another location block (This assumes php has been correctly setup).

Overall, your config seems overly complicated and I am sure whatever task it is doing can be done with a far more straightforward configuration.

I have done a basic clean up / consolidation but not having a full picture, some bits may be off. Should give you some ideas though.

Important thing though regarding the PHP is pulling it out of the nested location.

Also, using Status Code 418 instead of 405 for redirection as 405 can be legitimately generated for other reasons.

Using a separate server block for the example.com to www.example.com redirection for better performance.
