Regenerate Batch invoices after all was cancelled

[ISPConnect]

HI I would like some assistance if any one can help. 

We recently had to change our VAT %, my invoices generated before I could make the changes. I then cancelled all the invoices and made all the changes. How do I go about to regenerate all these invoices , the cron was set , as well as the deu date, the only ones that do generate is for new orders. I deleted the invoice of one customer to see if this will work but no luck.

Hey @ISPConnect ,

Thanks for your post on WHMCS.Community.

Once an invoice is generated and cancelled WHMCS will not allow it to be recreated, to fix this you need to use a Workaround which is to move the next due date by one day will allow an invoice to be created for almost the exact same time period.  So in this case if your invoice was due on 01/03/18  (1st March) set it to 02/03/18 (2nd March) and you should then be able to regenerate the invoices.
