I am facing an error problem with Ajax, which is not running on the shared server without errors. But it's running well in my local host. Everything is perfect on my local host, but not with shared server. I couldn't figure out the issue, but I know problem is from my end. Can you suggest how to troubleshoot this problem?
I'm going to make the assumption you are using Apache as your web server. You should ensure you have something similar to the following in your configuration:
AddType application/x-httpd-php .php
It looks like your files are being served as plain text instead of being handed off to PHP.
