Default frontend language does not follow Joomla settings.[solved]

[Donald]

I have set a non-English language as the default in Joomla, and enabled language switcher and such. Everything works great, except that it always default to english when visiting for the first time, or after clearing all cookies.
Is this a known issue?
Is there a way to debug why this happens? Are there any other variables involved?

1. Did you install the VirtueMart language pack for your second language using the Joomla extension manager?
2. Did you add your second language into the VirtueMart configuration > Language setup?
3. Do you have 'Use English as a fallback for untranslated strings' enabled in VirtueMart configuration > Language setup?
4. Enable Joomla 'Debug System' and 'Debug Language' in the Joomla configuration settings and then check, if your second language frontend xx-XX.com_virtuemart.ini is loaded.
Certain typos in language files can prevent them from loading correctly.

Yes, the virtuemart.ini was loaded for the non-english language. The language switcher works fine, both languages are shown everywhere when manually switching. It's just that it's always default english. Boggles.

what is your setting for the joomla System - Language Filter plugin?  Browser or site language?

Aha!

It was browser based, now it's site option based. Thank you very much for your help. Especially since I realize this was a pure Joomla config issue that had little to nothing to do with VM   Sorry and thank you
