Fix "Key JLanguage has not been registered with the contain"

[Pascal - Netenvie]

Hi,
After upgrade to 3.4.1 one extension return this error :
"Key JLanguage has not been registered with the container".

I want to try some fix but don't know where to start.
Is someone exactly know what mean this error message and where to look ?

Regards.

Without knowing what the extension is then it is impossible to even guess.

My best advice would be to contact the developer of that extension

hello i have same error on media manager popup (image A in article, menu image A etc)

As Brian noted, you'll need to find the extension causing it and contact its developer. The message is being thrown by an extension using Joomla's Dependency Injection Container; the core platform is not using it at this time.

ok the bug appair in menu (article link) or in article edition (joomla core)
but you think it's an other extension problem ?

Yes. The article editor can be extended through plugins and it is entirely possible that one of those plugins are causing the error. I'd suggest starting by filtering the plugin manager by type "editors-xtd" and disabling any plugin with an ID greater than 10000 (these will be non-core plugins). This should help figure out which one is causing problems.
