Dear all,
When I am trying to create a lesson, the preview image of a sequence is not loading. I am not sure if the problem occurs while creating the image or while loading the image. I do not see any error in the server log file while creating the image, but the server sometimes returns this error after waiting several minutes when loading the image:
[STDERR] org.apache.batik.bridge.BridgeException: null:0
The URI "http://url/lams/images/svg/icon_htmlnb.png"
on element <image> can't be opened because:
The URI can't be opened:
