Bug exists only for Light Micro-finance.
When you try to disburse any Loan for the existing or for the new client, then after you click 'Submit' button, an incorrect error message appears and it contains only a red dot () and there is no possibility to continue. See attached screenshot.
This error message should be corrected.
This error is related to mifosBeanConfig.custom.xml and mifosChartOfAccounts.custom.xml files. After placing those files (proper versions) in Mifos custom folder, everything works properly.
