WordPress has become incredibly intricate over the many years CharlesWorks has been developing websites. As a platform of its own, it consists of thousands of PHP programs (scripts) running in unison.
As open source, the source code is in the public domain. This gives all of us access to it – including those who would use it maliciously. Hence the need for the dreaded security updates.
It is not uncommon in very complex sites for issues to arise after the application of security updates to the WordPress core, themes or plugins. You must bear in mind that each of those types of components are the culmination of many, many programmers. Looking at WordPress as the huge working system that it is can leave one in awe that so many moving parts can be harnessed in unison. Most of the time, anyway!
In very simple sites (like this one) there are seldom issues. In many cases simple sites can evolve into complicated monsters. We’ll have to see what happens here. The addition of a weather widget in the sidebar- a rather simple endeavor – will make it just a little more complicated!
