I'm suddenly receiving the following error for all my Flickr photo galleries. It had been working for months now it's broke! Is it something at Yahoo/Flickr or an adjustment I need to make on my end?

JFile: :read: Unable to open file: query.yahooapis.com/v1/public/yql?q=SELECT+%2A+FROM+query.multi+WHERE+queries%3D%27SELECT+%2A+FROM+flickr.photosets.info+WHERE+ ....

I'm running the following versions:

• K2: Version 2.6.1
• SIG Pro: Version 2.6.0 with a setting of jQuery library handling: Load 1.8.x latest
• Joomla! 2.5.8

Here's a few example links:

Locally uploaded (to my web server) photo sets display CORRECTLY ... just the FLICKR account ones are generating errors!

I did double check the API key and even re-entered it to make sure there wasn't any adjustments!

I've done nothing ... and it's working today. Not sure if it was a Flickr problem, or something with my web host provider.
