WordPress error, unable to install theme and plugins.

June 12, 2021

Today, I got calls from my clients in Canada and the US with their WordPress websites. The issue is that they cannot update plugins, WordPress requires them to enter FTP credentials.
I went in and checked the issue. Found out Caching software is also failing to save cache and cannot upload any type of media (files) to WordPress upload.


  • When attempting to update WordPress or WordPress plugins, you may be asked for FTP connection details.
  • Unable to upload files using WordPress upload media.
  • Error on Caching plugin. ei: WP Rocket unable to save cache due to file system permission issue.
