Strange error when integrating php script

Hello, we are using this codecanyon script ( https://codecanyon.net/item/php-social-stream/12069791 ) in a lot of our projects. Everything is fine but this seems to not work with ee.

When we try to call the script in an ee template we have this error. https://ibb.co/2NCnnwD

EE notifies us talks about unclosed brackets but in the template there is no condition at all.

Any idea will be welcome.

Cheers
