TCPDF stopped working after updating yii2

Yii 2.0 General Discussions

Hi,

I have an application that was generating pdf files using TCPDF, working well on Yii 2.0.1.

After a composer update which upgraded Yii version to Yii 2.0.11, the generated files are not downloaded, garbage is shown on a web page instead.

I also tried to integrate kartik-v/yii2-mpdf with the same results. If I test to generate the PDF file on PHP outside the Yii application, it works OK.

Any help is welcome

I’d compare headers sent.
