Bug with 'Recurring templates' once stopped

Hi,

I was working on the Akaunting and noticed that there is a bug or error on both sections -> Sales and Purchase under 'Recurring Templates'.
I added recurring invoices on both sections starting in the future but then in a hurry I stopped (ended) them with todays date; and both sections have crashed now, and I have no more access to those but I can access other sections.
Error message states -
'500 Internal Server Error
Oops! Something went wrong'
I hope this will help you to improve your product.

Kind regards,
Rita
