[SOLVED] Cannot read property 'length' of undefined


New member
I've been bugging about this issue for a day now and still cannot find an answer to it.
Trying to find the cause of the following issue:

It stops the page from being loaded and it doesnt show the image on the site.
url is [link removed]

Its running the standard jQuery 1.12.4-wp bundle. (i've also tried it with jQuery 3.5.1 using jQuery updater plugin).

What can cause the webrotate360 image not to load?

Kind regards,

Hi Yari, it looks like the issue is due to basewidth parameter in the shortcode being in % vs px that the plugin requires. For the explanation of basewidth, please see bullet 3 here:


PS: you may have configured Base Width in the plugin settings in admin, i.e not in the shortcode directly.
