Hi,
We are using WHMCS 5.0.4. In this version the domain checker integration code doesn't work. domainchecker.php will redirect to the client login page. The only ways to fix this will be to upgrade to WHMCS 5.1 or 5.2. Only problem is that there is no supported module for these version for our payment gateway (iDeal with Mollie). We are forced to stay on 5.0.4.
Now we are wondering if anyone can help us solve the domain checker integration for 5.0.4. WHMCS support told us they wont work on any issues for 5.0.
We hope anybody can help us out.
