1.6 settings page?

I’m also seeing the same “minimal” settings page with v1.6 on a single site WordPress set up. Another site on the same server also using v1.6 displays the usual “user friendly” version of the settings page. Would like to know why there is a difference.

+1!

I just came here to report the same issue.

I’m confused about where the interface went, especially since I use Mailgun on a multiste network and need to use separate domains for each subsite.

Same thing as above, I rant the Test Configuration and everything works normally, so it looks like the settings are still in the database somewhere.

I would also agree that this does not look intentional, and if it was, this is no bueno.

Same issue here.
Please can you (@mailgun) provide follow up on this? (Bring back the UI settings please?)
Thank you.

Update…
What is “MAILGUN_SECURE”? What are the parameters?
The other settings are self explanatory, except the above.

For anyone else that needs some help, I took a look at the database and found the existing data still stored in wp_options. Look for the option name “mailgun”. Or just search for it.

You can duplicate the existing, working settings, from the database, to look something similar to the below syntax usage (but DO NOT edit your database):

define('MAILGUN_REGION', 'us');
define('MAILGUN_USEAPI', '1');
define('MAILGUN_APIKEY', 'key-XXXXXXXXXXXXXXXXXXXXXX');
define('MAILGUN_DOMAIN', 'mg.yourdomain.com');
define('MAILGUN_USERNAME', '[email protected]');
define('MAILGUN_PASSWORD', 'XXXXXXXXXXXXXXXXXXXXXX');
define('MAILGUN_SECURE', '1');
define('MAILGUN_SECTYPE', 'ssl');
define('MAILGUN_FROM_NAME', 'SomeName');
define('MAILGUN_FROM_ADDRESS', '[email protected]');

Naturally, you would substitute (adding) your correct settings instead of using the above as is.

I observed more settings than were advised in the version 1.6 updated screen

I hope this helps someone in some small way.

Me too

me as well – multisite

Same here. We use this on many multisites and need different mailgun credentials per site. With this new settings interface this is impossible without additional logic in the wp-config file.

I agree with the above as I do not believe this was an intended change.

Same problem here, also using WordPress Multisite 4.9.8.
You cannot change the settings on wp-config.php on a Multisite instalation, because all sites share the same wp-config.php file and we need different settings for each domain.
Went back to version 1.5.14 until this is fixed.

From what I can see it looks like this was an intentional change.

Look in includes/options-page.php on line 68 and 408. You will see the following:
if (!$isMultisite):

Basically forcing the user to use wp-config on a multi-site install. Removing this logic actually brings back the admin fields and can be edited properly. I believe instead of one or the other give both options. Some people use the wp-config.php while others use the admin. Leave them both in there as you have support for both.

I removed the logic for now but this was definitely poorly implemented on their end. Below is a working file without the updated broken multi-site admin interface.

UPDATED: I changed the file to check for the MAILGUN_DOMAIN Constant on Multisite and if it doesn’t exist bring back the interface.

You the real MVP, rhinogroup.

Thanks for sharing your fix while we impatiently await Mailgun to [hopefully] roll out a new update!

@rhinogroup, thanks for this solution. I still would like to hear from Mailgun whether this was intentional or not though.

Fixed in 1.6.1, thanks!

Version 1.7 of the Mailgun plugin again removes the settings page for Multisite installations.
This is no good because we need different settings for each domain.

To fix this, I went to “includes/admin.php” and commented the logic that removes the settings page on Multisite. Basically I just commented lines 46 an 55. As simples as this:

//if( (!defined('MULTISITE') || !MULTISITE) && (!defined('MAILGUN_USEAPI') || !MAILGUN_USEAPI) ):
	// Hook into admin_init and register settings and potentially register an admin_notice
	add_action('admin_init', array(&$this, 'admin_init'));

	// Activate the options page
	add_action('admin_menu', array(&$this, 'admin_menu'));

	// Register an AJAX action for testing mail sending capabilities
	add_action('wp_ajax_mailgun-test', array(&$this, 'ajax_send_test'));
//endif;

But I ask the plugin developers to please make the settings page available again.
I don’t understand why you removed it? It doesn’t make sense and it still works with this simple fix.

+1 to @gonperesgmailcom. I saw that they removed the multisite settings once again in the 1.7 changelog, so I refrained from updating this go around. We need different domains for each install too, so I’m seriously questioning why they would intentionally do this..

@gonperesgmailcom , I tried your fix but it did not seem to take on my install. Was there anything else you did?

Never mind, commented out the entire thing by mistake.
