I was a subscriber of Nuevo a year or so ago and have a couple of sites using their templates. After updating Joomla on one site I received the following errors

Warning: Invalid argument supplied for foreach() in .../templates/archetype/includes/helper.php on line 273

Notice: Undefined index: Roboto in .../templates/archetype/includes/helper.php on line 298

Notice: Undefined index: query in .../templates/archetype/includes/helper.php on line 300

Notice: Undefined index: family in ..../templates/archetype/includes/helper.php on line 301

I've had to take the site offline and may have to quickly find a new template to replace Archtype. I'm also hesitant to update any other site which might use a Nuevo template. But I'm hoping someone will have an easy and quick answer to correct the problem. Thanks.

Hello Anne Marie,

Please open a ticket so we can sort this out.
In the meanwhile please turn off error reporting in order to hide these notices.

Hi Krikor,

Forgot about the error reporting being on! I'm not a current subscriber and can't afford a subscription at this time unfortunately. So I probably can't open a ticket. Getting rid of the notices will at least give me some breathing room until I have time to re-do the site. Thanks.

I've just tested my sites which used Nuevvo templates using Google's Mobile test tool and all 3 of them failed. The rest of my sites which don't use the Nuevvo templates passed. So I have to assume that it is the templates which are the issue? Before I have to re-do 3 sites by Tuesday is there some quick way of making them mobile friendly that I'm missing?

Which sites are you reffering to?
www.google.com/webmasters/tools/mobile-friendly/?url=http%3A%2F%2Fdemo.nuevvo.com%2Fsites%2Fj3x%2Farchetype
Archetype since it is responsive it is mobile friendly, same as Radiowave ( www.google.com/webmasters/tools/mobile-friendly/?url=http%3A%2F%2Fdemo.nuevvo.com%2Fsites%2Fj3x%2Fradiowave ) and the rest of our templates.

This said, it is possibly a 3rd party extension causing this. Eg: A Flash video, or banner. This means that you do NOT need to redo any of your sites.
