Dear Joomshaper team
I'm also researching the issue here and found the following:
- The problem lies in the Virtuemart payment methods. If you create these, it works, if you open them again to configure them, the system writes the settings to the database.
- The settings are stored in the "[PREFIX]_virtuemart_paymentmethods" table - "payment_element" field.
- The first time you create the status_pending="" is set. When configuring, this changes to status_pending="U".
And it is precisely this pending status that causes the error "Default Layout file is not exists! Please goto to template manager and create a new layout first."
If you set this manually via the database to status_pending="" everything works again under Helix Ultimate Template.
Did the test with Beez3, with this template it always works without errors.
I hope this information helps with troubleshooting, as the error can be reproduced by saving/configuring a payment method again
Hope the setting/bug in the Helix Ultimate system is found. Thank you very much
Greetings Kurt
