Need help to resolve a strange issue - Decimal sign based on language

[eldermaster]

Hello all,

I really need your help guys.

Suddenly in my backoffice on product details - price has comma for decimals.

I did not changed anything from yesterday till tonight.

When I try to save the price an error pop up saying that I cannot save it because the format is not right.

Till now I had the dot sign.

The single way to work is to switch back to english, and the dot is there and I can work.

If I switch back the language the dot is replaced by comma. Check pics

I am frustrated with this issue.

I tried everything.... of course i include here the currency menu, old tools.php file, etc.

Any help will be highly appreciated,

Thank you,
