Trouble when use free version

Hello Support,

I have trouble adding logo to my website.
Previously, a logo was uploaded and setted ans was appearing on the front size.
Then, I had to change the logo and from this time, it was not possible to display an other logo…

Do you know anything about a bug in relation with the action “Add a logo”?
Would you please try to find a solution with me ?

Let me know,

Thanks in advance,

Chris
