SItecake editor toolbar disappeared

Hello I managed to connect to the sitecake editor, I played a bit with the functionalities, then did not published my changes and closed the toolbar and shortly after my webpage.

Once I got back to mydomain/sitecake.php I log in and the editor toolbar doesn’t display anymore and I’m unable to move anything.

I found out that removing the sitecake-backup and sitecake-temp folders on my ftp solve the problem for the next connection but it’s bugged again the next time

Any hint?

Thank you in advance
