Hi all,
i was previously on a previous version to whmcs and was dealing with a error anytime a customer went to checkout with paypal.
after applying hotfix's and upgrading to the newest version of whmcs those issues are not present.
But now i get the error Paypal Webhook Signature verification failed. On loads of payments, i have removed and re-linked the billing panel to paypal API but seems the issues not going away.
payments are being taken but billing system is not applying them to invoices resorting in a lot of manual adding transactions to invoices
i have checked Hotfixs for this issue
