Hello, I just installed the Sumup plugin on my client’s website, and like other people I’m not able to connect it to the Sumup account. When I click the “Connect account” button, it opens the “Online payment” page ( https://me.sumup.com/fr-ch/settings/online-payments ), and then nothing else happens. The page remains stuck like this, the content of the WC module never loads: Also, the following error appears twice on the plugins page: Warning : Trying to access array offset on false in /…/wp-content/plugins/sumup-payment-gateway-for-woocommerce/includes/class-wc-sumup-logger.php on line 25 Here are the technical specifications of the website: WP version: 6.9.4 Plugin version: 2.9.1 PHP version: 8.4 I have deactivated the plugin for now, and really need a quick fix of this bug, otherwise I will have to look for another payment method. Thank you in advance for your help. The page I need help with: [ log in to see the link] Hi, I updated to version 2.12.0, the warning on the plugin page no longer appears but I still cannot connect the plugin to my clients’ Sumup account.

I tested with Firefox, Chrome and Safari, and had the same problem with the three browsers. Can you please provide support for this issue?
