Bug when importing content

We have encountered a bug when trying to import channels. When select the channel you want to import, Kolibri tries to load the content and then stops on a blank screen as shown below.

I have tried refreshing and it seemed not to work but while I pressed ctrl+alt+prtSc keys to do the below screenshot, somehow it then loaded the directories within the channel. @Michael please add anything i might have missed out.

Hello,

Would you mind checking if there are any errors in your server logs? https://kolibri.readthedocs.io/en/latest/manage/get_support.html#locate-kolibri-log-files

You can also check for browser errors: https://documentation.concrete5.org/tutorials/how-open-browser-console-view-errors

thank you
