./wp --version
WP-CLI 2.7.1

Hey @ihorlv,

I'd recommend reaching out to Ionos to see if they can help resolve the issue. It seems like your WP-CLI Phar file isn't being executed by CLI SAPI.

Here's a related issue: #5237 (comment)

@danielbachhuber
Thank you for your hint. I found the solution in the Ionos docs. The CLI version of PHP in their servers is /usr/bin/php8.0-cli
So, the correct command is /usr/bin/php8.0-cli ./wp-cli.phar

[danielbachhuber]

Glad you were able to figure it out!
