Magento 2. When I try to open Component Manager I get a 500 Internal Server Error on


and the page does not load. enter image description here

I am using php 5.6

  • 500 error means some errors inside PHP most of the time. Please check var/log/exception.log and post the related error messages first(if any).

I have fixed this issue by following below steps:

  • Open /setup/index.php/componentGrid/components in new tab
  • It showed me an actual error, in my case, it was the last extension installed through composer.
  • I have removed that from composer
  • After updating composer, I have to execute following commands as well.
  • bin/magento setup:upgrade
  • bin/magento setup:static-content:deploy

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.json and composer.lock then you are DONE!

I am using Magento 2.1.7
