Problems you may encounter when upgrading to the official version of WordPress 5.3 and how to safely upgrade WordPress

Looking at the CMS programs used by our personal and corporate websites, most of them still use WordPress. Its characteristic is that it has a relatively open application and theme platform, which can basically meet the needs of most users for function and theme selection. At the same time, WordPress is constantly working hard to upgrade and improve to meet the needs of users. This is something we cannot do with other individual or company CMSs, especially free open source CMSs, which give up maintenance and updates when there are certain bottlenecks and no benefits. This is also the reason why many of our domestic CMSs have not been developed. It is not The product is not good.

However, WordPress seems to have encountered something recently. When we open the official website to download the latest version of the program or install the plug-in theme, the 429 Too Many Requests problem will appear. The problems caused by this are quite serious. For example, we cannot download the latest version of the software from the official website, and we cannot install plug-ins and themes when we upgrade them in the background. Of course we definitely have a way to solve it, but we just don’t have the freedom we had before.

In view of the current situation, WordPress has not come up with a way to deal with it. Of course, there should be ways to deal with it later. Currently, WordPress has been upgraded to version 5.3, but this version seems to have a lot of modifications, causing some plug-in incompatibility issues. This is not old Zuo (laozuo.org) wrote this article today. It is also a short summary of the problems encountered recently in helping enterprise customers upgrade programs.
