greetings Mr Daniel, happy new year. I honestly, have not played with any of the vsersions above v3.3.12. I tried them a little and when i didnt see that editor, i run back to 3.3.12. I also noticed an issue with the newer xibo versions and MySQL8xx…few days ago, i decided to check in and try new versions and went straight ahead with v4.4.0 and knowing it works with MySQL8.4, i tried it and had no success. but i remembered that bug as i experienced the same mysql8 with xibo v4xx in the past, i tried with MySQL5.7 and it worked fine.
i am not sure if anyone had such bad luck trying to kick start xibo 4xx docker with MySQL8xx. my current production xibo is v3.3.12. using an external MySQL aka remote_mySQL. i always hope there would be an v3.3.14 or upper but i guess it ended at 3.3.12.
I will comb through xibo4.4.0 for the RSS ticker editor to learn how to get the same effect of the WYSWYG editor and i bet i will be the happiest man alive.
