If you’re getting this error after activating the Lagom (or Lagoon) theme on WHMCS:
Error: Call to undefined method WHMCS\Utility\Captcha\LocalImage::getSiteKey()
Here’s the fix
This happens because newer WHMCS versions (8.9+) changed how the captcha system works — the LocalImage type no longer has the method getSiteKey(), which older themes still try to call.
Open your theme’s file:
/templates/yourtheme/includes/head.tpl
Find this line:
recaptchaSiteKey = "{if $captcha}{$captcha->recaptcha->getSiteKey()}{/if}";
Replace it with:
{capture assign=recaptchaKey}
{if isset($captcha)
&& isset($captcha->recaptcha)
&& is_object($captcha->recaptcha)
&& method_exists($captcha->recaptcha,'getSiteKey')}
{$captcha->recaptcha->getSiteKey()}
{/if}
{/capture}
recaptchaSiteKey = "{$recaptchaKey}";
Then clear your template cache (in WHMCS admin: Utilities → System → Clear Template Cache) and reload the page. Or mannualy remove all files inside templates_c directory.
This makes the theme compatible with newer WHMCS versions — it will only use getSiteKey() if reCAPTCHA is active and won’t break when using LocalImage.
