Magento 2. When I try to open Component Manager I get a
500 Internal Server Error on
I am using php 5.6
I have fixed this issue by following below steps:
/setup/index.php/componentGrid/componentsin new tab
For me the problem was a language package called
magento2translations/language_es_es downloaded outside of Magento marketplace.
You need to open http://your.domain.com/setup/index.php/componentGrid/components
and see which package is causing the problem, then remove all reference to this package in
composer.lock then you are DONE!
I am using Magento 2.1.7
