I know this will sound as a strange question, but I looked everywhere - and I cannot find the problem.
When I am logged in, for any google service that I use, google thinks my default language is Greek (which is not my language at all). This means the following - the whole google interface is translated to Greek - the is true for adwords, adsense, analytics, webmaster tools, recaptcha service, ... - this is not related to browser/computer as I tried other computers and browsers (firefox and chrome). - I see in any google URL that "?hl=el" is added (which forces google to use Greek) - the only way to stop this, is manually change "?hl=el" to "?hl=nl" (Dutch language) Deleting the "?hl=el" doesn't help, I need to change it.
This is related to my personal account. But I cannot find an option to change this setting. I can't remember setting this myself...
I have multiple google accounts, and this is only on one specific account (sadly, my most important - cfr adwords, adsense, analytics...).
Question is clear: how do I change this?
