-You will need to investigate if xml default or other layout containing ''cacheable="false"''. If with default layout, it mostly like the whole sites won't be cached at all. If on other routes, then some certain route, such as all product pages won't be cached.
+It is possible one of your layouts contains the string ''cacheable="false"''. If this is found in the default layout, it's likely the whole site won't be cached at all. If it appears in another layout, then a particular route (such as all product pages) won't be cached.
-ssh to 'app' folder of your Magento2 installation.
+To see if this is happening in one of your layouts, ssh to the ''app'' folder of your Magento2 installation, and execute the following:
   grep -r cacheable * | grep xml | grep -v js | grep false
-  [root@server1 app]# grep -r cacheable * | grep xml | grep false | grep -v js | grep xml
+You will see something similar to this:

-You can analyze the code to determine that it won't be caused by ''RealexPayments'' or ''Plumrocket'' and it should be caused by ''Lof\RewardPoints''. If you are familiar with Magento 2 code structure, any route from ''view/frontend/layout/catalog_product_view.xml'' of any module will be combine together and loaded to every product page.
+You can analyze the code to determine that ''RealexPayments'' or ''Plumrocket'' won't cause your product pages to be uncacheable, but that ''Lof\RewardPoints'' //will// affect your product pages. This is because in the Magento 2 code structure, any route from ''view/frontend/layout/catalog_product_view.xml'' in any module will be combined together and loaded to every product page.

-Any catalog_product_view.xml of the above will take effect for every page, excluding catalog_product_view.xml-ORIG and catalog_product_view.xml-remove since they have different names.
+Any ''catalog_product_view.xml'' in the above list will take effect for every page. The only module to appear in either of the above lists as well as the original search for ''cacheable'' is ''Lof/RewardPoints''.
-Hence we identified the following which caused the problem.
-  code/Lof/RewardPointsBehavior/view/frontend/layout/catalog_product_view.xml:                    <block class="Lof\RewardPointsBehavior\Block\Buttons\Facebook\Like" name="lrw.fb.scripts" template="scripts.phtml" cacheable="false" />
-If no cache for the whole site, most likely you will find one of the ''module's default.xml'' ''cacheable="false"''.
+Hence we have identified the cause of the problem. It is ''code/Lof/RewardPointsBehavior/view/frontend/layout/catalog_product_view.xml'', which contains:
