Thank you so much for all this information!
converting2wp it′s not the child theme, I know I should have done that before “playing” with the code ó_ò
The thing is I still have open the functions.php editor and was hoping to find a solution before dump everything, just to restore the theme (and then I will “play” with the date and posting code. I have tried to copy the original code and a few things more (like changing another part to see if the error changes) but doesnt matter what I do is always the same error.
Any thoughts?
If not I wil reinstall everything as you said. Thanks so much brainstain! ??
