It was the version right before this one,
if I give you access to the site could you please check it?
I am no it literate and my coder said that as my php version is ok he does not know neather.
In any case the problem happened probably when I upgraded php last week or when my coder upgraded xoops,
as I did not check before I don't know the eventual origin of the problem,
thank you for your time and support.
