Could not connect sendy with Plugin

Hello @hieult,

I trust you’re doing well!

I’ve tested integration with Sendy on my test site and could not replicate this issue.

Please re-check the Sned credentials you’ve added, to make sure these are added correctly.

If the issue still persists, please check if there are errors on the developer’s console when the error "Something went wrong" is showing. To do so, please right-click on your site, Inspect > Console. Please see attached screenshot:

Please enable WordPress debug mode, add the following lines in the wp-config.php file

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

Please make sure that you insert these lines above /* That's all, stop editing! Happy blogging. */. Try to reproduce this error again by trying to connect to Sendy. This way all errors will be saved in the debug.log file inside the /wp-content/ directory.

Let us know the errors that you will find.

Kind regards,
Nastia

Hi @hieult,

Unfortunately, there’s nothing in the debug log that suggests that there are issues, notices will not affect functionality on the site so this is not related.

Do you have any other plugins that are currently connected or use Sendy connection as it’s possible that two options calling the same API could be conflicting?

Could you perform a conflict test by disabling all plugin except for Hustle, switch to default WP theme and see if the connection works after that?
If it does enable them one by one until you see which one is causing the issue.

I would suggest performing this test on a staging site or if you don’t have one make sure to create a full backup before you start with testing.

Cheers,
Predrag
