Having worked with hundreds of different WordPress websites, we have seen many different combinations of plugins and themes. As you are probably aware, not all of these are created as equals. There are definitely some that stand out as better options for many reasons.
We don’t necessarily provide a comprehensive list of plugin and theme do’s and don’ts (there are plenty of online articles for this). Instead we look at your unique requirements and combination of theme and plugins. We generally know which ones play ‘nicely’ together and which do not. If we find either a poorly coded plugin or theme or a combination that is known to have conflicts, not only will we notify you about it, but we will either fix the conflict or recommend a more stable combination.
Additionally, we also hold a healthy toolkit of licenses that we are happy to share if and when needed.
