from the screenshot looks like you aren't loading the chosen library which produces the interactive dropdowns
check your console etc for JS errors, clear browser cache, try another browser etc etc

I tried with many browsers, always the same error.
I take 2 pictures from the results :

I don't know

do u have French translations or have u tried with the English?

The json is returning the select info...

Maybe a problem with your backend template or some of your backend extensions. Try one of the default templates and disable the extensions.

[extonjaez]

after debuging, the error comes from :

"KMFasTrans Translate" admin module (3.1.1-PRO)
Categorie works when i disable it
Best regards

The developer needs to use VmConfig::loadConfig not the old VmConfg::setDbLanguageTag function. I just guess this, becasue another dev made this error. Despite we wrote clearly in our tutorial that VmConfig::loadConfig is mandatory (the tutorial is more than 5 years old)

i have the exact same problem but i dont have any backend modules

[Milbo]

Maybe when you scroll down in your console? There is some ajax, maybe it is not visible due the console settings (I think it can be filtered out)

Try to disable PHP errors in joomla and in server, if you have any error message the returned datas are bad.
