Problem Solved : JavaScript error in WordPress

Hello there.....
I was facing the JavaScript error problem since two days in the WordPress .There was written on the top right corner of my account "Error Occurred". I first saw that error , ignored it.
Then I entered into my account and start doing work.When I was working, the comment section was displaying but due to JavaScript error, I was unable to update the comments and add a new post.
I was in trouble that day.

This  will guide you how to diagnose JavaScript issues in different browsers.

1) Make sure that you are not using a proxy server:
The first and the foremost thing that you have to keep in your mind you are not using the proxy server.If you are using the proxy server, there is a possibility that there may be some sites like FB(facebook),twitter and other social networking sites may be banned.Because, your site may be using the plugins of one the same.As they are banned,you could not use the site features properly because the banned sites' plugins may also be banned.

THEN , to solve this problem,you have to activate the intended plugin from that proxy server.

2)Try Another Browser

To make sure that this is a JavaScript error, and not a browser error, first of all try opening your site in another browser.

  • If the site is not having the same issue in the new browser you know that the error is browser specific
  • If the site is having the same error it is not an error that is specific to one browser

Do the following steps to solve this problem :
 
Step A) Enable SCRIPT_DEBUG

 Turn on script debugging. Open wp-config.php and add the following line before "stop editing! Happy blogging".

define('SCRIPT_DEBUG', true);

 Check to see if there is still having an issue.

Issue is fixed - Turn off script debugging and report the issue on the support forum by telling that you turned on script debugging and it solved the problem.
Still facing the Issue - proceed to Step B.

Step B) Diagnosis
Now,which browsers you are experiencing issues with you,you can start to diagnose the issue.

Firefox

1) Open the Console
Go to Tools > Web Developer > Error Console

2)Identify the Error
The error console will open. If errors are not displaying, try reloading the page. The errors may be generated on the loading of page.
