Flexslider images do not load in FF, Chrome and Opera but loads in IE9

Seeing the same behavior, more or less - save that slider now doesn't load in Firefox.

Seems like things were OK until I started building some panels (on internal pages) - could this be a clue? Odd...

UPDATE: Never mind. I enabled jCaption but hadn't set it up yet. In trying to create captions on (presumably) all images, the browsers evidently freaked. Sorry...

I don't know. I haven't heard of this issue before.

Verify the version of the flexslider library that you're using. Also posting details on how you're displaying the slider would help.

I just updated to FlixiSlider 7.2 in a try to solve this issue.
I had before that 7.1 version installed.
My problem it that the slide do not show in Google Chrome but fine in Internet Explore (both newest versions).
If I look I can see it is being loaded to the page and that the CSS is set correctly to show the active content but still it do not show up.
Any one that can help?

Yes, I did try that and even tried to set it to Slide and then back to Fade and played around with the other settings.
I use the FlexiSlider in a View and in the View settings I have also tried different slide animations.
The result is the same. It is only visible in Internet Explore.

Can you make sure it's not a CSS issue? Check if the slider is at least rendered to the page and perhaps active but not visible (use Firebug of the Chrome Dev Tools to find out).

Sorry for getting back late. It was different CSS issues that somehow got mixed up.
After resetting and doing it again it works fine. Didn't find the reason for the error but have it solved now.

Same. Images didn't load at all in Chrome and only on browser refresh in Firefox.
The issue for me was the"Smooth height" setting. It wasn't firing and the css height property stayed at 0.
It's a shame, it's a really sexy well rendered effect.
I'm using jquery 1.7 served by jquery update.

I have the same issue. Tried the suggestions given above, without success.

I have a slider containing 5 images. When the image is not displayed, I notice that there is an error with the following image:

Warning: session_start(): Cannot send session cache limiter - headers already sent

This only happens after loading Chrome. When I refresh the page, everything is fine. Clearing caches does not affect the situation in my case.

UPDATE:
It seems that it has something to do with referring to images with and without the prefix www. I have changed every URL call to an absolute URL without the domain.

Before I had http://www.example.com/image1.jpg and http://example.com/image2.jpg. When I called the website with www.example.com the images without the www were not shown initially (but the were after a refresh). I now have both images as /image1.jpg and image2.jpg and everything is find.

Perhaps this can be solved by adjusting the RewriteCond/Rule in htaccess to redirect everything to one place.

I think I have solved this by using the htaccess file.

There is a section which does the redirect:

 # If your site can be accessed both with and without the 'www.' prefix, you
  # can use one of the following settings to redirect users to your preferred
  # URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option:

Choose one to your liking. If you have chosen one, all redirections will force it to the correct place, even if you have added www or not.

I had the issue where sliders weren't appearing upon refresh. Disabling "smooth height" per DrupalHack fixed it. Thank you!
