Does yii require attribution?

I am a little confused with the license :

This is for a site not a binary file. I would love to give yii attribution, but it says:


Use contributors' names, logos or trademarks.


I believe what it means you cann’ t put contributors name on your website without their consent, if you like you can put a ‘powered by yii’ link on your site like many others.

// this should give you enough to put in your footer

<?= Yii::powered() ?>

Does that mean I cant have a license/about page with the above copyright notice?

you don’t need to include the license on your website just ‘powered by yii’ is enough

Public attribution is not required.

What that statement means is that you can’t say that your product is good because it’s built with Yii. Stating the fact itself is fine.
