Problems reading publications

If you are experiencing problems accessing or loading publications you may need to check that there are no browser plugins or extensions interfering with access to Calaméo. You might also need to check for anything that could be blocking YouTube (if you are experiencing problems with video) for example.

It may also be necessary to update your web browser to the most recent version.

Error 911

Error 912

When encountering this error trying to load a viewer theme, this can mean one of two things:

  1. There is a problem accessing a default Calaméo viewer theme (in which case, refer to Error 910 for recommendations).

- Or -

  1. The viewer is unable to load or locate your own customized theme. For problems loading a custom theme, this could mean either that the URL of your theme is incorrect, or that Calaméo does not have access to your custom theme. For the latter, you must allow Calaméo access by placing a “crossdomain.xml” file containing the following text at the root of your domain:
<?xml version="1.0"?>
 <!DOCTYPE cross-domain-policy SYSTEM "">
   <allow-access-from domain="*" />

You can also download the “crossdomain.xml” file here:
