[Koha] Auto renewal not working

[Michael Kuhn]

Hi

Our library works with Koha 20.05.02 on Debian GNU/Linux 10.

The automatic renewal doesn't work as expected. These are the relevant 
circulation rules:

* Loan period: 28
* Unit: Days
* Renewals allowed (count): 5
* Renewal period: 28
* No renewal before: (empty) - according to 
https://bywatersolutions.com/education/setting-up-auto-renewals-with-new-features 
it is said that a blank value will indicate that the auto-renewal will 
occur on the day it is due.
* Automatic renewal: Yes
* No automatic renewal after: (empty)
* No automatic renewal after (hard limit): (empty)

In the staff client we can see the checkouts of the users - but for 
every checkout it says "0 Can no longer be auto-renewed - number of 
checkout days exceeded (5 of 5 renewals remaining)". In fact NONE of 
these checkouts were EVER auto-renewed.

As we see in table "issues" the value in column "auto_renew" is "1". But 
the value in column "auto_renew_error" changes from NULL to 
"auto_too_soon" after the checkout day, then after some days to 
"auto_too_late". No auto renewal is ever performed.

We have set system preference "RenewalLog" to "Log" but no renewal 
actions are ever logged.

How can we get auto renewal get to work properly?

Best wishes: Michael
