Bold and italics in article has no rendering

Hi, I like Songwriter and my buddies too ??

Thids may be a FAQ but I can’t find a way to solve it.

I am facing the following problem :

In the editor the text is : (strong)
Lorem ipsum dolor sit amet, consectetur adipiscing elit,

Preview shows :

Lorem ipsum dolor sit amet, consectetur adipiscing elit

but the rendering on the site still no :

Lorem ipsum dolor sit amet, consectetur adipiscing elit << ?? no bold ??

Am I doing something wrong ?

Thanks in advance

Jacques
