Hi @seo and welcome to the Atlassian Community!

I'm not sure this is the right place to ask about your application not being deployed properly. We don't know anything about your environment and setup.

Do you have more details? And is this something that worked before and is now broken?

[SEO TEAM]

What you need to know about the environment and setup. 

Previously it was done by my developer but I am managing but somehow its not working.

How do you deploy your code?

[SEO TEAM]

I made the changes in the template and them submitted the commit. After that, I approve than and merge with the master file. 

[Charlie Misonne]

yes ok so your change is merged with master.

But what happens after that merge? Is a deploy mechanism being trigger with a (Bitbucket) pipeline?
And if so, does that pipeline show any errors?

It is very unlikely that your code change on master will have an effect on your application just like that. There must be some kind of process performing the steps to apply the change in your application.
Any insights on that?

[SEO TEAM]

I don't see either any deploy mechanism or any pipeline. 

Guide me where i can find or do i need to take any step.

[Charlie Misonne]

Do you have anything under pipelines in Bitbucket?

It is likely that another process was put in place. Could be with scripts that were run manually or another CI/CD tool.

Best thing would be to ask your developer.
