I have a fresh and updated setup. Added the WordPress app. Tried to install a new theme (Appearance/Themes/Add themes) but get error message: “Installation failed: Could not create directory.”
WordPress allows me to select FTP/FTPS/SSH2. I select SSH2 because SSH is enabled by default on FreedomBox. I can connect to the box via ssh.
Same problem when trying to update a plugin: “Update failed: There has been a critical error on this website. Please check your site admin email inbox for instructions.Learn more about troubleshooting WordPress.”
Most probably a permission issue, can someone reproduce and suggest a workaround/solution?
