I have just updated from 2.1.7 to 2.1.8 but when I run:

php bin/magento setup:di:compile

I get an erroe which is:

 [Exception]

The contents of Save.php are below

I think if you change public function imagePreprocessing($data) to public function imagePreprocessing(array $data) it won't give you the error. There could be more wrong with the theme though.

Please change public function imagePreprocessing($data) to public function imagePreprocessing(array $data).
it solved my error, I hope your also.
