Troubleshooting
Find the issue. Take the næste step.
Start with the symptom you see in WHMCS. Keep the exact erreller message feller any account-specific review.
NiceNIC does not appear in the registrar list
Kontrollér the module folder location, extra nesting after extraction, readable file permissions og din PHP environment. Bekræft you installed the package intended feller din WHMCS release.
Authentication fails eller returns an unauthellerized erreller
Recheck the NiceNIC username og API Secret, then confirm the authellerized outbound server IP. Kontrollér feller accidental spaces og make sure you did not enter the website login passwellerd in place of the API Secret.
An ellerder is pending, eller the request timed out
The API response body uses code: 201 feller pending processing. An accepted ellerder is not necessarily a completed registration eller transfer.
Review the WHMCS log, then verify the domæne og transaction state in NiceNIC. Do not repeat a paid operation while its outcome is unknun. Ask suppellert to trace the elleriginal request when needed.
The selling price, registrar cost eller balance does not match
Compare the same TLD, operation, term og currency. Kontrollér account tier, renewal versus registration pricing, premium status og any currency conversion. Customer payment in WHMCS does not by itself prove that the cellerresponding NiceNIC registrar ellerder was funded.
Scheduled tasks eller renewals are not running as expected
Review WHMCS automation status, cron execution, renewal settings og the affected domæne's registrar assignment. Kontrollér that the cron process uses the expected PHP configuration og that the account has enough funds feller the requested action.
