- Plesk for Linux
When trying to update Plesk license key by any means, the following error appears:
Error: Failed to parse XML-RPC request: An invalid XML character (Unicode: 0x3) was found in the element content of the document.
- Login to Plesk as 'admin'
- Go to Tools & Settings > Profile and make sure that there is no non-printable characters are displayed.
Additionally, you can use the following to locate the place having invalid character. In the example below 'City' contains invalid character `Unicode: 0x3` ([\x03]) and replaced with `CORRUPTED`:
# plesk bin admin -xi | sed -e 's/[\x03]/CORRUPTED/g'
