Hello @kalpsmacaw
Thank you for reaching out and I am happy to help!
Are you getting this error only when updating the W3TC?
The “Update failed: Could not copy file” error typically indicates an issue with file permissions, server resources, or conflicts preventing the system from writing or copying necessary files during an update process.
To address this issue, consider the following:
- Check File Permissions: Ensure that the directories and files involved in the update have the correct write permissions.. You may need to adjust permissions using an FTP client or through your hosting control panel.
- Verify Server Space: Confirm that your server or disk has sufficient available space for the update files. Insufficient disk space can prevent files from being copied.
You can always download the plugin and try to manually update the files
Let me know if this helps!
Thanks!
