Steps to reproduce the bug: - Let's consider a user U with fr_BE as lang - Log as U and active developper tool - Go on any record, click on debug button - Select Technical translation - Choose a translation and click on the transifex url button Bug: The URL contained the iso code fr_BE but this iso code didn't match any code in Transifex. From: https://www.transifex.com/odoo/odoo-14/languages/ We can see that the only iso codes with a '_' are: 'zh_CN', 'zh_TW', 'pt_BR' opw:2448533 closes odoo/odoo#65308 X-original-commit: d609a75ccbfaa62b6070de4769880a94d896ff73 Signed-off-by: Simon Goffin (sig) <sig@openerp.com> Co-authored-by: mart-e <mat@odoo.com>
