Your plugin broke another plugin, help me to fix it.

A very common support request I get. So the problem is, something went wrong in JavaScript and it’s giving you an error. So how do you find out what error came in? Let me show you

Debugging on Firefox

1. Install firebug add-on and restart your browser
2. Follow the image instruction:
   

Debugging on Chrome

1. You don’t need to install any additional add-on/extension for Google Chrome
2. Right click on the page and click “Inspect Element“
3. Follow the image:
   

Clicking on the script name will show you which script is generating this error. So happy finding bugs 🙂
