I am using Magento 2.1.1, When i enabled all caches excepts
Full page caching then my site front-end is working fine but when I enabled
Full page caching and refresh all cache also then front-end is not working.
Can anyone tell me what is the issue and how to fix this?
After enable error reporting, I am getting issue with one extension only.
Fatal error: Call to a member function getIdentities() on null in /home/salusdcw/public_html/vendor/magento/module-catalog/Block/Product/View.php on line 373
