Fatal Error Connecting with Sendinblue

Just to add, wp version is 5.5, PHP version is 7.3.23, and there are only 3-4 plugins activated on this site.

$double_optin_templates = ['' => esc_html__('Select...', 'mailoptin')] + Connect::get_instance()->get_double_optin_template();

Looks like an error in the code where using addition (+) on an array which I confirmed by removing the array & testing with
esc_html__('Select...', 'mailoptin') + Connect::get_instance()->get_double_optin_template();
But of course, this brings up a Warning: A non-numeric value encountered.

Looks like it’s connected though, because this code only runs if (true == $connected) but still surely needs to be looked at. Can’t access the page with fatal error.

Hello, we sincerely apologize for this error you are getting.

Can you make a little change to the plugin from the plugin editor in your dashboard?

If you can, kindly follow these steps:

1. Go to the plugin editor and select MailOptin.
2. Under the plugin files section, Open this folder path: src/connections/SendinblueConnect/
3. And click on Connect.php under the SendinblueConnect folder.
4. Locate line 155, where you see this $double_optin_templates = [];
5. From that line 155, replace the code from line 155 till 166 with this particular code:

$double_optin_templates = [];

if (isset($response['body']->templates) && ! empty($response['body']->templates)) {

   foreach ($response['body']->templates as $template) {
      $double_optin_templates[$template->id] = $template->name;
   }
}
            
return $double_optin_templates;

6. Then click on the Update File Button below to effect changes. This would clear up the error.

But if you can’t make the changes yourself, please send us a developer login to our support email ([email protected]) to assist. We would love to help.

Let me know if this works.
