    Hi

    We got this weird upload issue in the Media section in backoffice. Both running local on Visual Studio and on the live server.

    If we restart the site, we can upload a single small file, and then is fails after that.

    Here is the log, any suggestions/help would be much appreciated.

    Trying to solve this.

    If i use the drag and drop method in an RTE it works fine, also with multiple images.

    So I maybe it is something with the "Media Picker" Property editor.

    Is there anyway to restore this, if it for some reason broke?

    I solved this.

    in web.config i removed

    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="false" />
    

    and upload works again. I am not sure why or when this line came into my web.config file.
