php 8.0 or 8.1 compatible
`Hi just wanted to flag that, the plugin doesn’t work with php8.x

Just updated the site to php8.1, the option forms are not loading in the admin dashbaord or on the frontend.

Error details
…/wp-content/plugins/campaign-monitor-wp/providers/campaignmonitor/campaignmonitor/class/services_json.php. Error message: Array and string offset access syntax with curly braces is no longer supported

I opened the file: service_json.php and replaced all curly braces ‘{‘ with square brackets ‘[‘ according to help I found on the internet:
“Since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated”
My page seems to work both on the backend and frontend with this modification, but it would be highly appreciated and big help for many users using the Optin Plugin.

Hi Takayuki Miyoshi.
Thank you for your quick response.
I forgot to mention that the message was surrounded with red border line.

I am having Office 365 subscription, which includes the email exchange server.
Recently Microsoft has constantly updated this environment and the belonging applications, so the root cause for the error is very likely occurring in the email server.

Best regards
