Hello,
My problem seems to be similar to this one.
He resolved it by re-uploading the sitecake folder because the upload was incomplete, but has been completed.
I checked my DB which apparently is on php 7. Is this correct ? I can change to 5.6. The website is hosted by one.com.
You can see that the browser always add a slash bar at the end of the url…
Thanks for helping me,
Bests
