[Solved] Language switch on Help Documents not working

[papa2fois]

I am puzzled , now it works without the plugins !!!
I cleared the firefox cache and it still works.....
What i have done wrong ??

Edit:
Now I have deleted the xthelpdocs.php plugin and it is still working.
The explanation is only into the removal of the comment tags in ./inc/languages/french/helpdocs.lang.php file that I did once but unsuccessfully for whaterever reason.

Thanks you .m. for your time to help me find the trick.
