Theme error when install and activate

[ventanacultural.pe]

Hi there! I’m trying to use the wpstream theme but when I activate it, then I recieve 3 errors on the top of any page in my site.
This is what it returns above my nav menu:

Warning: Creating default object from empty value in /home/customer/www/streaming.adrianm.sgedu.site/public_html/wp-content/themes/wpstream-wordpresstheme/admin/redux-framework/inc/class.redux_filesystem.php on line 29

Warning: session_start(): Cannot start session when headers already sent in /home/customer/www/streaming.adrianm.sgedu.site/public_html/wp-content/themes/wpstream-wordpresstheme/classes/login_register.php on line 32

Please give me a hand with it

Hello.

I am experiencing the same issue when activating theme. I have made fresh wordpress install and there are no plugins installed. Could you please take a look why is this happening?

Hello there,

I have attempted to replicate this action yet I am not receiving the same error. Please get in contact with support@wpstream.net with a screenshot of this error and they will be able to help you troubleshoot. Thank you for your cooperation.

Looks like the problem was with PHP version. I switched from PHP 8.0 to 7.4 and now I was able to activate theme.
