In version 3.1.1 I had to fix two files to get it working properly:
In 1) Line 49: changed ‘id_aeuc_email’ to 'id_mail’
in 2) Lines 63, 66, 67: changed ‘$mail.id_aeuc_email’ to ‘$mail.id_mail’
Otherwise the bankwire module (maybe all other payment methods too) did not work in checkout and the settings (additional e-mail content) in the aeuc module were not saved.
I think in /modules/advancedeucompliance/classes/AeucCMSRoleEmailEntity.php there is a similar bug in line 49 where ‘id_aeuc_cmsrole_email’ should be changed to ‘id’. In my installation I could not see any effects before and after changing it.
Could one of the developers test this and update the module if necessary.
