When you make changes deeply of a CMS, it loses the likelihood of getting refreshed. Regardless of whether it is refreshed, changes will be lost at any rate. What's more, updates are important to dispose of the bugs that regularly emerge. Notwithstanding, making changes is presently conceivable without influencing the updates. It is done using vQmod. You don't need to stress over the original documents since no progressions are made to them straightforwardly. Rather, a virtual duplicate is made by vQmod. A vQmod directs PHP record, then overwrites the virtual duplicates at whatever point changes are made profoundly. In this manner, leaving the refreshed part unaffected.
