    V8 upload issue

    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.
