Ok, thank for these informations.
I changed an option in the Simplest Gallery Parameters and all it works fine now.
To informate other users, I just checked “Use WP’s default jQuery” instead of “Use Gallery Specific jQuery”.
Thank again for you help.

Christophe

“Simplest Gallery plugin!Please install and activate Simplest Gallery plugin!Please install and activate Simplest Gallery plugin!”
