Send Email Reminders problem

[macdpl]

I have a problem with email notofications.
SMTP is configured corectly. Test e-mails are send.
But notifications about new cases not.
Cron is working because Send Email Reminders in log are Succes
but... Send Email Notifications Failed in log


in system log i found:
[2021-09-07 18:37:02] ERROR: CronManager: Failed job running, job [6137b099cde296362]. Error Details: Function name must be a string at (mydomain...)/public_html/application/Espo/Core/Htmlizer/Htmlizer.php:624

What is wrong?

Did you change the reminder template (at Administration > Template Manager)?
