Flex Slider can not add new optionset

Hi, I upgraded form alpha1 to alpha3.
After this update I detected that none of the images in the flexsliders I already had (they were working well before) don't have image styles anymore.
I edited my flexslider configuration, checked that the image styles (for main and thumbnail images) still were correctly selected (they were) and tryed to resave the flexslider configuration. Then I got these two error messages:

• To use Thumbnail Captions you must install FlexSlider version 2.2 or higher.
• To use Display both thumbnail captions and normal captions you must install FlexSlider version 2.2 or higher.

I also checked image styles and they are ok. I updated the flexslider library provided in Github too without success.

Because of the version and the error messages of this issue, I think my post is related with this, but I don't have such a permissions configuration (I have the default permissions -> library folder and flexslider library folder are 705), and I can't follow the solution provided above.

Can you help me? Thanks in advance

The elemnt validated might be too aggressive. I'll see if I can adjust it.

Note that image styles in the option sets aren't begin used anymore. The style is set at the view and field level now.

I'm experiencing the same issue

Can you post the output of the following from within your libraries directory

ls -la flexslider

Same problem here. Here's the output of: ls -la flexslider

ls -la flexslider

I am also having this issue. I am getting the following:

Notice: Undefined index: version in _flexslider_validate_minimum_version_22() (line 550 of /home/content/51/11814351/html/sites/all/modules/flexslider/flexslider.admin.inc).
To use Thumbnail Captions you must install FlexSlider version 2.2 or higher.

I've tried uninstalling and reinstalling the module as well as making sure the .js file is correct. Kinda dead in the water. I've used this module with no issue on several other sites recently don't know why I'm getting this issue with this one.

I'm having this problem also. I was onversion 2.0 of FlexSlider library so I upgraded to version 2.2. But it didn't fix the problem. I did clear cache.

Not only can I not create a new flexslider profile - I can't even make modifications to my existing profiles.

I'm getting the same errors as in #9.

Any ideas?

Ah - problem fixed. I was being a dork: when I upgraded the flexslider library to version 2.2 I simply forgot that library folder names have to be all lower case. So changing it from FlexSlider to flexslider made these errors disappear.

I figured this out by reading related issue https://drupal.org/node/2118891
