Hi NR
Thank you for sharing the error log.
After reviewing it, we found that the Error 500 is triggered when ConferenceDiscountEligibility version 1.0.3 is loaded on Leconfe 1.5.0. The log explicitly states that the plugin supports Leconfe 1.4.6 but detects version 1.5.0:
Plugin 1.0.3 supports Leconfe 1.4.6; detected 1.5.0.
.../plugins/ConferenceDiscountEligibility/src/Services/CompatibilityGuard.php:39
.../plugins/ConferenceDiscountEligibility/src/ConferenceDiscountEligibilityPlugin.php:57
@Bruno , could you please help to review and update the plugin to ensure compatibility with Leconfe 1.5.0?
Regards,
Almadani
