Hi, if the background image is in SVG format, it must be clean and in full strict svg standard. If we allow background images to be uploaded without being compliant, it will cause bigger problems within the attempt or response.
what you can do: open the svg in a notepad or any text editor and clean all no complaint tags (and html, comments etc) and then save it and then try to upload it again.
And if you want to share the original svg, I can point to you where the additional non compliant code is.
Thanks for your quick response. I just downloaded a sample SVG from the web:

Is a background image necessary and if yes, can it be any format other than SVG?
Hi,
Unfortunately I get the same error as before with the modified SVG. The alert message pops up on preview page and also on the page when the user starts the quiz attempt with the corresponding question. If I create a quiz with no background. Opening the quiz ist no problem. The user can draw something. The alert popup comes up as soon as the user finishes the attempts and submits all.
I have installed plugin version 2021091000 on Moodle 3.9.9
Thanks
Hi,
We just installed the plugin to give it a try. No matter what SVG image we upload (even if we do not provide any background image) we are confronted with a browser alert saying
Error in background image. Background image most likely not in clean SVG format.
Now the question is if we are using the question type incorrectly or there is indeed a problem (bug) with the plugin.
Thanks for your help
