    /umbraco/backoffice/UmbracoTrees/ApplicationTree/GetApplicationTrees - using File picker


    We have recently updated from Umbraco 7.2 to 7.3 on our two servers.

    We are now facing the problem: /umbraco/backoffice/UmbracoTrees/ApplicationTree/GetApplicationTrees

    on one of the servers when we try to locate a file using File picker (

    I have been through code/files on each server and compared but none files seems to be missing.

    Has anybody faced the same issue?

    Hi Simon

    How did you do the upgrade? Was it manually?

    I also assume that the error you're getting is a 404 file not found on the path that you mention? Is it possible for you to attach a screendump of the issue? It might make it easier to get your context.

    If it's a 404 error then the file is probably missing somehow - But it might be that you'll need to bump the version number in the /config/ClientDependency.config file - Just increment the number with 1 so if it currently says "238290" for instance then make it "238291". Does that help?

    Otherwise it might also be a good idea to go to the /App_Data/temp folder and wipe the content of the "ClientDependency" folder.

    Looking forward to hearing from you and hope this helps!
