You have something connected in your configuration that requires one of the php extensions - GD or ImageMagick for its work, the error tells you that you need to install at least one of them, on the official php website you can read in great detail about installing these extensions :
GD: php.net/manual/ru/book.image.php
ImageMagick: php.net/manual/ru/book.imagick.php
