Hi [client’s name] – I suggest doing maintenance on your WordPress site as a proactive way of keeping it running smooth and fast. Every so often, WordPress will send out an update to it’s script for any number of reasons. Could be to patch a vulnerability, it could be to add more functionality to the back-end or to the end user, or to take away out-dated/non-functional features. That is 1 of the updates – WordPress itself. Others are from the functions that do no come “out-of-the-box,” like your contact form – we call these “non-out-of-the-box” features plugins. The script/code for plugins will need to be updated as WordPress is updated. So so so many reasons for this. One could be that the updates to WordPress changed a portion of code that a widget, if left out of date, will struggle to process. An example – Do you have an iPad? I just bought a new one because the one I bought 5 years ago could no longer run any of the apps. That’s because the apps, if they’re good, are made with the most modern and up to date scripting & that in time became too much for the old hardware to handle. So in this case, WordPress is our hardware and plugins are our software.
