Hi @vkWeb would you need any help with this, there is a conflict that needs to be resolved, and the review comment to be addressed.

Let us know.

[vkWeb]

@raisedadead Yes, I need help with this merge conflict. How can I resolve this? And Yes, I'll make the requested changes. Actually, my local environment is down, it's showing that plugin not found I'll re-clone my fork and will install it all over again.
Sorry for the delay.

[raisedadead]

You start with rebasing your branch, same as current staging. Follow the rebasing instructions in the docs, except use it on your pr branch.

When you get to the conflict, resolve them in your editor. Add your changes, make sure the old change is not overwritten by yours.

And push back on this PR branch git push --force.

However,
A simpler way would be close this PR and start fresh of staging, after you refresh your local, since you are cloning anyways again and you don't have much code change.

Reachout to the Contributors Chat room for help.

@raisedadead Thanks for the help - Okay, I'm closing this PR. I'll submit a new one within few days.
