In special cases, WordPress, plugin or theme updates can cause problems. This is partly due to various factors. For example, a website may contain many plugins and functions of various techniques and disciplines which may conflict or a new update may contain errors. Compatibility in this case means the extent to which plugins and techniques can be used together.
If an update to your WordPress website is causing problems, I will roll back the update, fix it on the staging server and then make the change on your live website. With the basic package you get 1 hour free compatibility support, which in most cases can be enough, if it takes longer, the work will be discussed with you in advance and then charged separately at my regular hourly rate. In some cases, the WordPress plugin or theme may no longer be supported by the developer, in which case I may not be able to provide a solution. In such cases I will propose alternative solutions.
