Couple of MailChimp integration questions

All mc files are 0byte files with no content and permission 664
I've personally set up the crons in Espo and on the server. I'm the admin or What do you mean with "Crontab"-user?

Could you check your batches in Playground?

Open Batches, select any, open in new tab the value from "response_body_url"

I get this file...

Write in PM the "response_body_url", please.

[tanya]

also check the parameter allow_url_fopen in php.ini

The Solution: PHP.ini
allow_url_fopen must set to ON

All works fine now.
