If we often see various version upgrades when using WordPress to build blogs and personal websites, or sometimes one or two version updates a month. WordPress is the most popular open-source CMS program used by most users in the current CMS. It is precisely because of constant upgrades, updates, and improvements to meet the security and functional needs of users, so many users can use it.
There are many WordPress users, and many people keep an eye on whether vulnerabilities are controllable. WordPress is constantly being patched and upgraded, which leads to various upgrade reminders. We recommend that you take upgrade measures after seeing the upgrade reminder and immediately fix bugs and various functional bugs. Of course, we also encountered various problems when upgrading the WordPress program, and even caused the website to fail to open normally.
Therefore, it is important to select a correct and stable WordPress upgrade method. Here, Chiang Kai will sort out two frequently used methods for upgrading the WordPres website program, which are automatic and manual.
1. Preparations for WordPress upgrade
We need to make several preparations before upgrading the WordPress program, so that we can save data restoration in case of an upgrade failure or website problems.
1. The website backs up data locally or synchronizes it to other Web environments. In this case, we can restore the data (website backup method) if the upgrade fails ).
2. Pause all plug-ins and enable them one by one after the upgrade is complete. Some of the special plug-ins installed on some websites may cause system upgrade errors and incompatibility.
2. Automatic WordPress upgrade process
The automatic upgrade method is common and simple and fast. After logging on to the WordPress website background, we will see a new version reminder. Then you can perform the upgrade according to the Wizard.
1. Check the new version.
As shown in the preceding figure, click "Upgrade Now.
2. Upgrade Now
We can also see on the upgrade interface, the official also reminded us to back up the database and files (official backup documentation: https://codex.wordpress.org/WordPress_Backups ). Normally, you can click the upgrade button to update all the latest version files, and sometimes prompt for database upgrade.
3. Start the plug-in
After the upgrade file is correct, our website can be opened normally. Then we can enable the plug-ins one by one. If the plug-in is enabled and the website becomes inaccessible or incorrect, it may be caused by incompatibility between the current plug-in and the new version. We need to replace or temporarily disable this plug-in.
Third, the WordPress manual upgrade process
In addition to the above automatic upgrades, we can also perform manual upgrades. It is a little complicated, but it is also commonly used.
1. Download the latest WordPress version.
| The code is as follows: |
Copy code |
New version download: https://cn.wordpress.org/
|
We need to download the latest version of the program to the local device, because we need to replace the files on the current website.
2. Delete the wp-uplodes and wp-admin directory files.
3. Replace all files except the wp-content directory
We will overwrite all the latest versions downloaded from the official website to the current site, except for the wp-content directory file.
4. Online update files
| The code is as follows: |
Copy code |
Http: // Current website address/wp-admin/upgrade. php
|
After the file is replaced, we will execute the above URL and prompt us to upgrade the database online.
5. Final work
After manual upgrade, we also need to start the plug-in and check for compatibility issues.
IV. Summary of the upgraded WordPress version
1. We cannot ignore important updates or common patch updates. After the new version is released, it must be upgraded immediately to ensure the security of the website and the stability of the program.
2. Back up the database and website files before upgrading WordPress to ensure that data can be restored in case of any problems on the website.
