Fix "click to unfollow is not working in /tag section"

[first-timers]

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from underrepresented groups in free and open-source software!

We know that the process of creating a pull request is one of the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new, and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

📋 Step by Step

Claiming an issue

Unless the issue is marked as reserved for someone, you can just say "I'd like to try this!" and then you've claimed it - no need to wait for someone to assign it to you. Just be sure you link your pull request (PR) to this issue so we can see where your solution is.

And open one early if possible - even before you've completed it with additional commits - and others can help you figure out any issues you may face.

• 📝 Update the file app/controllers/subscription_controller.rb in the plots2 repository (press the little pen Icon) and edit the line as shown below.

See this page for some help in taking your first steps!
