Solve the problem of "Problem with the SSL CA cert\\" when upgrading the WordPress version and installing the plug-in

Help a classmate move his WordPress blog from a virtual host to a VPS host environment. His VPS environment is built using the free version of AMH4.2 environment. He was informed that he could not download the latest WordPress 4.3 version and install the plug-in. , there is a prompt Problem with the SSL CA cert (path? access rights?) error. This is the first time that Snail has encountered this problem.

If this problem cannot be solved, all future upgrade themes and plug-in installations will have to be manually upgraded and activated, which is quite troublesome, so I used the search function to find a solution. This problem is mainly caused by system security restrictions. We can install and enable the AMChroot module in the background of the AMH panel, and then set the default security mode to compatibility mode.

Solution:

First, download and install the AMChroot module

Download and activate the AMChroot module from the AMH module background.

Second, set the compatibility mode

Set the compatibility mode here.

Finally, there is no problem when we upgrade the version, or download and install plug-ins online. For security reasons, we need to set the AMChroot module back to safe mode after the upgrade. Similarly, in non-AMH panel mode, Snail has also seen such problems occur in other environments. The foreigner's article mentioned that the solution is to restart the entire server, and then this problem can be solved. I have not encountered it specifically. So I just saw such a text solution. If you encounter it, you can try it.
