I have a wp-content/uploads
In it is the 2013,2014,2015 folders and backupwordpress folders and a siteorigin-widgets folder.
all your themes (2013,2014,2015) are supposed to be in a folder called /themes/ like this: /wp-content/themes/
what si “siteorigin-widgets”? why you have them in the uploads folder?
did you design the site or somebody else?
what you mean about changing permissions
have a read of this codex: https://codex.www.ads-software.com/Changing_File_Permissions
