I'm working on a wordpress site on which the wordpress core, plugins and theme are all outdated which I think is the reason that certain pictures look out of place and text doesn't look the same as it used to (not sure if this is correct).
The problem is that when I try to update these from the wordpress admin dashboard I get the error "Unable to locate WordPress content directory (wp-content)." I've used cyberduck and the FTP details to look for the file myself, or the wp-config.php file, which I also haven't been able to find. However going to the website as a visitor I'm able to see everything so I feel like the content should be generated from somewhere.
What would be the solution to resolving the issue and finding the files?
