Thanks I’ll try what you say… but that problem is Not only with Colorway theme.
I activated different themes I had and it gives me the same 404 message for all of them!
So, if it’s not the server and not the theme – it’s bound to be something in WordPress – I’m not certain but I think I had that problem since 2 or 3 updates. I used to be able to fix it, but this time not.
So I jst checked with the link to Sucuri for malwares… my site is ok.
