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.
