Frequently Asked Questions

Which browsers does Saber support

Saber has been built to work in many different browser / operating system combinations. In fact it’s easier just to list what isn’t supported.

Saber does not support the following:

  • Internet Explorer 8 and older
  • Users who have JavaScript disabled
  • Lynx and other text browsers

Can Saber be used over SSL (https)?

Yes it can! By default Saber will load over the SSL if your site is loaded over SSL. You can also choose to always or never load Saber over SSL, although I wouldn’t recommend choosing to never load Saber over SSL, unless you have a very good reason for doing so.

Will Saber work on areas of a site where users need to be logged in?

Yes Saber will work fine on pages and websites where the user needs to log in for access.

The only time when it may not work properly is if your site uses HTTP basic access authentication which also restricts access to images and CSS files. Please see the next question to see how to overcome this problem.

I've installed Saber but the screenshots aren't correct

This happens because the Saber server needs to be able to access your website’s assets (CSS, images, fonts, etc) in order to create the screenshot. There are two common scenarios which can stop Saber being able to reach your asset files:

Testing Saber on a local server:

Unfortunately you cannot test Saber on your local environment, as there is no way for the Saber server to access images and CSS files on your local machine. Instead try testing Saber on your online testing or staging server.

Using Saber on a server which is behind HTTP basic access authentication:

While Saber will work on sites that are behind authentication, HTTP basic access authentication is often set up as a blanket restriction for the whole site, restricting access to everything including images and CSS, instead of just restricting access to pages.

You can give Saber access credentials in order to access content behind basic authentication by adding an http_auth property in your Saber_options object, eg: if you wanted Saber to use the username ‘Saber’ and password ‘Pa55word’

var saber_options = {
    api_key:'YOUR API KEY HERE'

Missing or incorrect webfonts

Some browsers will not load webfonts from domains other than that of the host page. This means if your site uses self hosted webfonts, those fonts may not be displayed in screenshots. To fix this you need to allow Cross Origin Resource Sharing (CORS) on your webfonts:


location ~* \.(eot|ttf|woff|woff2|otf)$ {
  add_header Access-Control-Allow-Origin '*';


<FilesMatch ".(eot|ttf|woff|woff2|otf)">
  Header set Access-Control-Allow-Origin "*"

If you’re still having problems getting Saber working correctly please get in touch.

Can I just use Saber for internal bug tracking before releases?

You can absolutely just use Saber internally, how you achieve this depends on your setup. Eg: If you have an internal testing site you can just add the Saber embed code to that site. However if you want Saber on your live site but only shown to you team members you’ll need some kind of conditional logic that would only include the Saber embed code for specific users.

If you need any help setting this up, please get in touch.

If I eat myself, will I become twice as big, or disappear?

Well of course you would, er, hang on a second…
