Hi Taras, and thanks for answering.
Don't worry, I understand that the proper functioning of the component depends on this steps.
Now what I have is :
- Cache is NOT enabled
- URL rewriting is the one available by default on joomla : "Search Engine Friendly URLs" AND "Use URL rewriting"
- .htaccess is the one provided by default on Joomla (I also tried with one generated by AdminTools from Akeeba but had the same issu)
I found a strange alias for my category in the URL over the link of books :
My category for all book (400) is "Centre de ressources", the alias of the categorie in the parameter window is "centre-de-ressource", but when i go over a book, i can read "centre20%de20%resource" in the link...
If you have no idea, i will come back later on a public server, so maybe it will be more easy for you to help me ?
