How can fix not being able to upload/ manage media/ update CMS

Hi all,

It looks like the paths to files in the CMS have gone awry and I’m unable to upload/ delete media via EE, or update EE.

When I try to upload an image, for example, I get the following error message:

404: Item does not exist

Sorry, we could not find the item you are trying to access in the system.

URL: cp/files/upload/6

When trying to update the CMS version, I get this message:

Oops, looks like the updater couldn't complete.

We stopped on Preflight check.

Cannot get contents of path, the path is invalid: /var/sites/k/mywebsite.co.uk/public_html/themes/ee/

(worth noting that I have changed the alias/ name of the admin area folder, as recommended in the installation notes, also HTTPS is currently broken due the cert expiring).

Any ideas on how to remedy this before I have to do a full reinstall?!

I’m primarily a UX person and I’m putting this site together for a family member. Not a developer but I love structured content, so I’m an ExpressionEngine fanboy 😊.

Cheers!
