I use CiviCRM for Joomla. After upgrading CiviCrm 4.7.27 to CiviCRM 4.7.29 following problems came up in module CiviEvent using CiviDiscount:
- a EUR discount results in crazy figures (e.g. a 100 EUR discount from 780 turns to be 779.999.999.900,00 instead of 680)
- new discount codes dont work at all
The database cividiscount_item shows correct values, also the new values are added there. So problems seems to arise after hitting "APPLY" - Button with id and name "_qf_Register_reload" in the CiviEvent-form
It looks like being related to the decimal sign "." or ",", but till now I have no clue checkign the code in cividiscount.php around line 420
Everything worked fine before the upgrade of CiviCRM
