Web viewer 2.0 - Upgrade notice

Dear all,

Some users report me problems after upgrading the Web Viewer plugin from version 1.x to version 2.0.

If images that were previously properly displayed now appear as black, this is due to the fact that the cache needs to be rebuilt (the structure of the cache has changed).

You can safely delete the folder “WebViewerCache”, that is by default stored within the “OrthancStorage” folder (where Orthanc stores its database). This will force the reconstruction of the cache.

I will soon publish a patch that will automatically invalidate the cache after an upgrade of the plugin to avoid this issue.

Regards,
Sébastien-
