You'll need to provide the error. Make sure your perms are correct. Run sudo chown -R www-data: storage bootstrap public config && sudo find . -type d -exec chmod 0775 '{}' + -or -type f -exec chmod 0644 '{}' + from project root and then try to create a poll. If fails check log.

Aight.

The error was:

3 arguments are required, 2 given {"userId":3,"exception":"[object] (ArgumentCountError(code: 0): 3 arguments are required, 2 given at /var/www/html/app/Models/Poll.php:124) | Stack
-- | --

And I was able to solve it by changing
\sprintf('%%s%', $slug)
to
\sprintf('%%s%%', $slug)
on line 124 in /app/Models/Poll.php
