Clarity DNN Series - Caching trapAs many people already know, DNN is often used to improve the way regular caching modules work. A module caching starts off with a default value that is set by the system but the value of a module can be overridden by changing the digits in the settings section for modules. When different modules are developed, programmers can sometimes confuse the new module that they are developing with another one. This can occur when they are logged in as the admin. Simply make sure you're logged in to the proper module user and proceed.


Error with Starterkit templates

When a new value greater than zero is used, the module will utilize caching. The problem is the caching has not been enforced for individuals who are the Host or Admin.

You can easily prevent this DNN error from occurring by having a value of zero set in the manifest. Some developers and programmers even delete the node completely right before the module is installed onto to the website. Even if the module has been installed, the numbers in the individual case can be altered to zero as well.
