I am having problems finding the solution to two errors on a web site

  • 0

I am having problems finding the solution to two errors on a web site I am building on a Joomla 3.0.2 platform and using the Gantry Framework.

The first error is:

Type issue

‘null’ is not an object (evaluating ‘b.appendChild’)

The second error is:

Type issue

‘undefined’ is not an object (evaluating ‘rikgallery_slideshow.jump’)

I have never understood how to debug javascript errors, so I would really appreciate some help.

The site can be accessed at: http://lads.ergonomiq.net

If someone can help and needs super user access to the back end, please email me at ali.samii@ergonomiq.net

Thanks

    This is meant to simply point you in the right direction, further testing will be required to fully solve your issues.

    OK the first error is happening in responsive.js line 66

    menu.inject(document.getElement('.menu-block'));

    I would console.log(menu, document.getElement('.menu-block')) make sure both contain an element as expected. I am guessing one of those will be null.

    Second error

    AjaxURL: 'http://lads.ergonomiq.net//index.php?option=com_roksprocket&task=ajax&format=raw&ItemId=101'

    is returning unexpected JSON

    {"status":"error","message":"Unable to find class for item ","payload":null}

    I would test the error and only proceed if you have images in your returned JSON

    Line 136 of your home page.

    Hope this helps
