Jon,

Have attached a screenshot of the zipped file I used to install LabKey. When I installed LabKey 15.x a couple months back (barely learning) , I was following a tutorial which asked for the "externalModules" directory, so I created it myself... You think that could be it? Since I created the directory myself?

Also the owner of "externalModules" is "diego" not "www" which tomcat uses...

Have attached a screenshot of files "ls -l"

Thanks,
Diego
