There are several language files with values using an underscore to connect words as in ‘date_finish’
For some software translations those are words that can be translated but are passed to the URL so they can’t have accents or some special letters that could cause SEF issues.
In SuiteCRM are these words to be translated?
Any requirements regarding special characters?
Example in file \modules\Project\language (lines 132 to 135)
https://github.com/salesagility/SuiteCRM/blob/master/modules/Project/language/en_us.lang.php
'LBL_START_WIDGET' => 'date_start',
'LBL_FINISH_WIDGET' => 'date_finish',
'LBL_PREDECESSORS_WIDGET' => 'predecessors_',
'LBL_PERCENT_COMPLETE_WIDGET' => 'percent_complete',
