Error message in log

[dimoss]

Hi

I use J!3.9.12 and fabrik Github August version with php 7.1
The error log is full of the following:

PHP Warning:  Declaration of Fabrik\Helpers\Pagination::_item_active(Joomla\CMS\Pagination\PaginationObject $item) should be compatible with JPagination::_item_active(JPaginationObject $item) in /home/xxxx/domain.com/libraries/fabrik/fabrik/Helpers/Pagination.php on line 0
PHP Warning:  Declaration of Fabrik\Helpers\Pagination::_item_inactive(Joomla\CMS\Pagination\PaginationObject $item) should be compatible with JPagination::_item_inactive(JPaginationObject $item) in /home/xxxx/domain.com/libraries/fabrik/fabrik/Helpers/Pagination.php on line 0

Any idea what I should change to get rid of it?
Thanks
