OK! Finally done !
The work was finally done with your help, and the problem was solved with your great assistante ! Thanks a Lot !
Now I am fighting with the different differences between the two lines of configurations of config.php ( when true, when false ) and the 3 possibilities of califications of the keywords ( 1st. I know is always checked; 2nd. and 3rd. I am playing..... ), to reach the balance I need. But NOW the autolinking IS WORKING and all the rest is my work and need to study your article.
Thanks a lot for all this two days of work, Joseph, again !
