I dont know which of these i should do. If you mean all, thats a lot of work for a noob like me.
Thank you for your help, but i think its better to wait for an bugfree wp v3.6 update. I dont want to crash more then needed.
With the missing Icons, the editor is still useable, so i can write the html myself…with buttons its just quicker for me. I can live with that for about a couple of weeks/months.
Thanks again to you buddies.
