The correct way to successfully upgrade the system

Release time:2017年07月26日 Author:Catfish CMS Reading volume:68167

We know Catfish CMS system upgrade can go to the official website to download  the upgrade package, and then follow the upgrade instructions to  complete the system upgrade.


But in the  actual use of the user to reflect the system after the upgrade there  will not be able to visit the page situation, this is due to the old  system cache caused by the upgrade to the new version of the system is  still called the old system cache.


The solution is to upgrade the system before entering the background to clear the cache, as shown below:



Then extract the downloaded upgrade package and follow the upgrade instructions for system upgrades.


This is the correct upgrade process, you can avoid the old system on the impact of the upgraded system.


Another possible  problem is that some of the server quality is not very good, so it is  possible to upload the upgrade package file when there is no complete  upload success, encounter this situation, just re-upload the upgrade  package file on it.


Because the  official website using the system and we download the system is exactly  the same, so the official website upgrade is the same as everyone, using  the same upgrade package, and use the same upgrade method, so please do  not doubt the upgrade package procedures have any problems, And  then make things very complicated, when you have improper operation is  likely to destroy the original data, so for your site to normal  operation, when you are not fully grasp please do not operate at random.
