Resolved Can't import J5 users

Hello,
Did you apply the rule on the date fields? Can you post the latest template XML to check? To get the template XML file from RO CSVI templates list page select the import template and click on Backup templates button. Post the downloaded XML file.

I created the rule for both export ( on old site ) and import ( on new site ) and it didn't change anything.

Hello,
Thank you for posting the requested files. I was able to see the issue with your import file.

1. You have date in format Monday, 20 October 2025 in import file but database supported format is Y-m-d H:i:s. So this needs to converted to database supported date format. To convert the date use RO CSVI Multireplace rule plugin and Custom date format operation.
2. Since you have comma in dates and they are not wrapped in text enclosures each value is considered to be a column and that is breaking the import. See attached screenshot for date fields. Once you change the date format as explained above this should also be solved.

That is not error but a warning. You can set Error reporting to Simple in Details tab in Import template and run the import.

As far as 500 error I am thinking once you correct import file that should also be solved. Try and let me know on how that goes.

due to the highly sensitive nature of the user information I'll have to email it to you.
here is the error that showed up after settting debug to maximum

Status error: 200
