All currency converter classes are located in same file, not in separate files as they should. Base currency converter class is named "
kCurrencyRates" (starting with "
k"), but it is not part of In-Portal distribution, and belongs to In-Commerce module, so "
k" should be removed.
Also this class is registered not in unit config, but in kApplication class directly. At the end all classes from file "
\in-commerce\units\currencies\currency_rates.php" should be moved to "
\in-commerce\units\helpers" folder and named properly, because they are actually helpers.
