Hi everyone, not sure I submitted it the right way, sorry about that...
I just followed what was written after processing to the dry run giving: "[ERROR] Could not process
"C:\xampp\htdocs\wp\wp-content\plugins\backwpup\vendor\phpseclib\phpseclib\phpseclib\Crypt\Base.php" file, due
to:
"System error: "Syntax error, unexpected T_ELSE1"
Run Rector with "--debug" option and post the report here: /~https://github.com/rectorphp/rector/issues/new". On line: 272"

[LDSTATXPERT]

Hope it was the right thing to do!

Thank you for your report!

We'll need an isolated failing demo link from: http://getrector.com/demo,
that way we can reproduce the bug.

why you need to run rector on vendor dir? Latest phpseclib already require php 8.1+ /~https://github.com/phpseclib/phpseclib/blob/27d1ccc6889e8ac82e4bc39aeb6f334af6f12164/composer.json#L60

upgrade the dependency instead

[TomasVotruba]

Closing as Rector should not be run on /vendor

If you're not running Rector on /vendor, please share a minimal demo repository on Github with your rector.php setup. It will help us to get more information about your project
