Why some VM strings are in English? (whereas i have a Multilingual shop/site)

[extonjaez]

My devs says:

I think something in the language translation doesn't work properly with VM 4.0.7 10701 (or with 4.0.7.10713)

We have the fallback to English set to off in the configuration.
See sales price line using VMText and JText.

I think VM assigns language too early before Joomla establishes the current language. Because in the function vmLanguage::initialise, the language tag is always en-GB and that's because Joomla hasn't established the current language yet.

It's also likely this is caused by some plugin that calls VmConfig::loadConfig function  before the current language is established but VM should have some check for it in the vmLanguage class.

Thanks for your help 
regards
Arnaud

It can be an external plugin that set the language. Try to disable system plugins loading VIrtuemart config.
It can be a module too

"Base Custom Fields for All" plugin, used as a base for the Breakdesigns VM Custom Plugins.

note from dev
We suggest to keep the plugin disabled, as some issues were reported with the proper language detection, in multi-lingual sites.
After all, the plugin is not used by the Joomla's plugin system (does not have plugin triggers inside).
Hence it makes no difference if it is enabled or disabled.
