Hi @chawki Can you please DM me your template ? Please attach the template file with the message.

Please find attached.

@chawki putting it pending for you. Can you please try again once.

#5

hello, @chawki
That’s not the issue. Loadbalancer will be in the pending state until it’ll not get assigned the external IP address. but still you can access your application in the nodeport which is 30008 for testing.

Hi @Inderpreet.

Can you please double check?

@chawki
You did a mistake at
/** MySQL hostname */

It should getenv('MYSQL_HOST ')

You are right. I misspelled the parameter :frowning:

#10

My error is the same as you can see in my first post. Clearly this is a validation error.
any way i’ll not continue with this task :frowning:

@Inderpreet @rahul456

After deploying both the frontend and backend and making changes in wp-config.php file, when I try to access the wordpress website it’s displaying php code in the browser.

I really don’t know what am I doing wrong.

@Nautilus, your php is not configured correctly to work with nginx.
