Thanks, could you make another pull request and update https://github.com/Codeception/Codeception/blob/5.0/src/PHPUnit/Constraint/Page.php too ?

I fixed CI in 9.0 branch, please update your branch.

Hello

I checked https://github.com/Codeception/Codeception/blob/5.0/src/PHPUnit/Constraint/Page.php and mb_stripos seems to already have correct parameter (0 instead of null)

[jakubvojacek]

Branch updated, I hope

[jakubvojacek]

Any idea as to when this could be tagged? :)

Released as 9.0.7
