On behalf of the agency Pixelwald, a redesign was to be carried out for the portal Fernarbeit.net. The biggest hurdle was the plugins Digimember and WP Job Manager, which worked with very rigid template overrides. So only overrides from the theme root were possible. Since I usually use the starter theme Sage from roots.io, which provides a MVC folder structure, the override behavior had to be adjusted via hooks. By switching to a proper and modern theme, the loading time of the pages could be increased significantly.
