Yes, i’ve created 3 posts and indicate categories in each of them.
So, now, i’ve try with MAMP and this work good.
I see that, with XAMPP, there is somme access problems with database. So, i never arrived to find precisly wich is the file access failed. In the logs files, some indication about one file named under “/var/he/…something-other-like-no-sens” and which not exist (also, the way doesn’t exist to… very strange !). It is a files from MySQL database (sure) like other generated form this database… And also, the user who used the enrty have ALL GRANT PRIVILEGES.
So, i’m not an expert on database and MySQL… i think now that it is a problem included in XAMPP package inside MySQL files software.
I find no-one on the web who talk about this precisely. But sure now, something is buged, ot in WordPress, but in MySQL from XAMPP distrib.
Think you for your help.
