Project detail:

- Current plugins are around 24-26
- Hostaway plugin is the major plugin that is required and the one that slows the website.

We are open to hear about different CMS or solutions. Many of our client are worldwide and countries like Spain, Germany, Sweden and more all experience slow page load speed and some images do not work as it is either loads in poor quality or just poorly present. (all images have been compressed but quality of the images are good, this is an additional issue).
