This was working approximately a week ago, no code changes on the site, regular galleries work just fine, but I can't add any flickr galleries, even the example joomlaworks gallery.  The text is not an actual link, it is typed directly into the code, the plugin is active.  This is Joomla 1.5.23 with the latest version of sig pro...

This doesn't seem limited to just this site, I operate a different site, on a different server, same versions of the software and notice that all their galleries went back to links as well...

Any ideas would be much much much appreciated.

I am experiencing the exact same behavior. I had many Flickr galleries that all displayed without problem until today. I tried adding a local gallery - and it works fine. I reinstalled version 2.5.5 - same result.

Also, if I select a Load a Module position option, or set a Caption Word Limit - the following is displayed (and no other page content is rendered):

Fatal error: Class 'SimpleImageGalleryProHelper' not found in /home/thegrub2/public_html/sf/plugins/content/jw_sigpro.php on line 152

Any resolution for this? (wondering if there is some dependency on Blackberry for serving images...  :) )

There is an issue with Flickr galleries.
We are checking it now and we will try to solve it asap.

Thank you, the new version works great.

The Flickr galleries worked on Friday after installing the new version, but have stopped again. I assume this is another Flickr API related issue.

Another issue I have with this plugin. If I configure a Caption Word Limit value, I get the following error:

Fatal error: Call to undefined method SimpleImageGalleryProHelper::wordLimit() in /home/thegrub2/public_html/sf/plugins/content/jw_sigpro/includes/helper.php on line 156

If I set a Load Module Position value, I get the following error:
Fatal error: Class 'SimpleImageGalleryProHelper' not found in /home/thegrub2/public_html/sf/plugins/content/jw_sigpro.php on line 153

Also, the popup engines fail to provide image to image navigation whenever I set a Gallery Style other than default. That is, they display only the image clicked to generate the popup.

@dbgruber, did you use Flickr API key?

Please provide us with a link to your gallery page...
