The error message in the screenshot suggests that there is a JavaScript error on the live server. This could be caused by a number of things, such as a missing or incorrect JavaScript file, or a syntax error in the code.
To troubleshoot this issue, you can try the following steps:
-
Check the browser console for any JavaScript errors. This can give you more information about the specific error that is occurring.
-
Check that all the necessary JavaScript files are being loaded correctly on the live server. You can do this by inspecting the page source and checking that the file paths are correct.
-
Check that there are no syntax errors in your JavaScript code. You can use a tool like JSHint or ESLint to check for errors.
-
If you are using a JavaScript framework like Vue or React, make sure that it is set up correctly on the live server.
-
If you are still unable to resolve the issue, you can try rolling back to a previous version of your code that was working correctly on the live server.
Here is an example of how to use JSHint to check for syntax errors in your JavaScript code:
// Install JSHint using npm
npm install jshint --save-dev
// Run JSHint on your JavaScript file
jshint yourfile.js
This will output any syntax errors in your code that need to be fixed.
