Hi,
Normaly there’s no more problems:
1/ the left menu of the customisation section wasn’t working because an other plugin (effectio dashboard). I removed and voilà every works again. The problem wasn’t spécifique to the Fabulous Fluid Pro them but for all the themes
2/ i solved the second problem within woocommerce, a misconfiguration of my part.
So every thing seems to be OK!
Thank you for your help and sorry for my english 🙂
