I am working on a Magento 2 website. I found that the boolean product attributes are not visible on the extra specifications tab on the product page. After a while, I ended up on the official github of Magento with this issue: https://github.com/magento/magento2/pull/8623
Based on that, it should have been fixed. In my case, it hasn't. So, I tried to apply the fix myself.
I went to
vendor\magento\magento-catalog\block\product\view\attributes.php
and changed the line 89 from:
if (is_string($value) && strlen($value)) {
to
if ($value instanceof Phrase || (is_string($value) && strlen($value))) {
Then I ran an upgrade on console: ./bin/magento setup:upgrade
But I still have the problem. Anyone was able to solve it?
P.S. Magento CE 2.1.6
