I use this plugin that tells me when a plugin is out-of-date, when there is some unknown file and apparently the latest update also added the function of telling me about plugins that have not been updated for years. I have quite a few of these…
The risk is of course that WordPress develops and the plugin does not so it stops working. Or even worse, it breaks WordPress or becomes a security leak. I have started the task of removing plugins that were not (really) necessary and trying to replace those that are. The problem is that I have not found replacements for all plugins that I use and I am very happy with the functionality of some of them…
During the proces I also discovered that some things simply stopped working, such as the sitewide search function…
So, I have been removing and replacing some functionalities and I seriously need to get myself a new theme that is mobile friendly of its own, since the mobile-version-plugin that I used also came from the stone-age.
More work to be done!
