Javascript Error

Hi

Can anyone tell me how to fix this, when trying to view the app via LAN it normally works but I still get the error message and now it don't want to work anymore:

Javascript error!

Uncaught TypeError: Cannot properly read 'TagName' of null

http://19x.xxx.x.xxx:50000/, line 283 (col undefined)

This is either a bug in Construct2 or a problem in a third party plugin or behaviour - please report it to the developer!

I am running windows XP. Do I need to check my Java updates or what? I am totally clueless. Is the problem with the Tablet perhaps?

Java updates has nothing to do with your issue. I think it is more related to a plugin/behaviour. Try other browsers too.

ok. This is usually the result of 1 1 possible out comes.

1. Your using a non Scirra plugin that is outdated or has a bug

2. Your using Browser.execjs and there is an error in the js code line.

Try disabling all browser addons, sometimes they break pages.

Disabled everything and still getting the message. Read through this link numerous times and is beyond me https://www.scirra.com/manual/110/browser Cant hitnk what else can help. Jayder, when you say non Scirra plugin, what do you mean? Im totally new to this.
