Somebody knows why my overview are very long to appear ?
What "Preview" do you mean?
If you talk about "Preview in Browser", which one: "Preview Page" or " Preview Site"?
Be aware: To preview in browser, Muse has to export and check the output data, build and export HTML/CSS files, optimise images, check integrity, …,, hand it over to your browser and display it. This takes time. If you visite your already exported site, all these export processes are not necessary. Your browser only has to load the existing data.
Hi Franck, without seeing any screenshot of what you mean, it is hardly to say .
