Dear friends, we finished a migration but we had small issues with this local es_AR, we changed all values to es_ES in the locale fields from all tables (before migration), but, we still having an issue at Copyediting ( Draft Files) the info never arrives. we found in the error log this line.
Migration from version 2.4.7.1 to 3.1.2.1 was carried out and another user wants to be added from an administrator user but displays the following message ## user.profile.form.givenNameRequired ## () and the Apache log appears this description PHP Notice: Undefined index: en_AR in lib/pkp/classes/form/validation/FormValidatorLocale.inc.php on line 45, referer: management/settings/access.
Try deleting files with extension php inside the cache folder but still with the same problem.
