Hi Barry and thank’s for your response.
I tried the two things you suggests and it worked.
I switch to twenty fifteen, deactivate all plugins except The Events Calendar and Events Calendar PRO and I flush the permalinks. It didn’t solve my problem.
So I created a new set of recurring events and it worked, all the permalinks of this new event send me to their pages. I reactivated all my plugins and switch to my theme and it still worked (whitch is great by the way 🙂 ).
I wanted to try so I created an other recurring event with all my plugins activated and it also worked perfecty fine.
And then y remembered that I had a problem during the tranfer of my website from wamp to my server. The url changed so the permalinks did’t work after that (obviously). I’m a bit lazy so I did’t want to look in phpmyadmin and execute a bit of sql to reset them right and the creation of recurring events is so easy that I recreated the same event and then I deleted the old set (I’m a bit stupid to –‘). I must have deleted all the new events I just created except the first. That was my problem…
Sorry for the trouble and thank’s again Barry, you actualy helped me 🙂
