Can't connect CF7 to third party plugin

First, confirm you’re using the correct (i.e. latest) versions of all plugins — fairly often I’ve heard from people using either an old version of CF7 or an old version of my plugin; there was a major change to CF7 a while ago that required I update my plugin accordingly so you need to use the newer versions of both.

After that, open the browser developer tools (usually F12) and go to the sources/console tab to see if there are any Javascript errors both on page load and when you submit the form. Then, check the Network tab when you submit the form — you should see a new POST entry, and you can see the response. If it looks weird (i.e. not a JSON success response), then something server-side is broken.

If it’s something server side, you can try enabling WP_DEBUG and WP_DEBUG_LOG via your wp-config.php file and check the wp-contents/debug.log file to see more info about what broke.

Not working on multisite. No email, no debug. It seems the post is throwed just on the main blog.

Any hint about multisite?

I’m using latest CF7 + wordpress and there aren’t errors in javascript console.
The Post working in main site but it isn’t throwed in other blogs where CF7 is installed.

Are you sure my plugin is enabled for other sites in multi-site? Or is it only enabled for the main site?

i have tried network installation: it working just on the main site. Then i have tried single installation and not working at all.

Are you saying you can’t even see the plugin admin on your other sites, just the main one? Do you get debug emails from the plugin on the other sites?

No, i can see the plugin admin and i can configure it. I’m saying that the plugin not throw at all the POST to third party configured URL and it don’t send any debug email except in main blog.
