PHP errors in Ajax Response

Hello There,

Would you please check if the errors are coming from Fluent SMTP? I have deactivated all the plugins except Fluent SMTP and Query Monitor and then checked, the issue did not appear. When I activated another plugin, the error appears; kindly check the video. The errors might be coming form other plugin, can you please check and confirm?

I have used the below configuration for testing:
Fluent SMTP: 2.2.5
WordPress: 6.2.2
PHP: 8.2.8

Let me know the update.

Thank you

Hi there,

I disabled all plugins except for Fluent SMTP and Query Monitor. I also enabled the default WP theme (Twenty Twenty-Three).

The error is still there.

Tested in the browser Mozilla Firefox and Microsoft Edge.

Please re-open this as it’s not resolved. Thank you.

Hello There,

We need to test out the issue, would you please share the details here so that we can check it further?

Thank you

I’m having the exact same issue, and am using the latest version of Fluent SMTP. The following error shows up when retrying a failed email from the logs screen.
