Mailpoet not saving

Open your developers tools (if you are using Chrome), then click on XHR (this will filter your browser requests by AJAX requests. Then try to save your newsletters. You’ll see the error message. My bet is that your admin-ajax.php is probably returning a 403 error. Let us know!

Thaks for quick reply.

Im using chrome, Clicking XHR under the network tab and then trying to save a newsletter gives me a 404 error. Developers tools also give me one warning.

The following info is shown under the console tab.

Warning:
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.

Error:

prototype.js?ver=2.6.16:1528

Try to add this piece of code to the beginning of your .htaccess file that sits in the root directory of your WordPress installation:

<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>

I added the code at the top of the.htaccess file, but i still get the same warning and error message

I still have the same problems and i still get the same error and warning messages. Any ide on what i can do to make the mailpoet plugin work again?

We are already looking into this error message as it seems to be affecting other users as well.

Where will you post information about the solution when you find it?

It is a great plugin, so im looking foreward to a solution ??

I’m going through the same problem. Any solution?

The following error is also generated when filling out the registration form:

Oops! There is a problem with this form:
textStatus:error
errorThrown:Not Found
responseText:

Please!!! =/

Paulo: No solution for me either so far, im checking every day for a plugin update. But nothing so far. I realy hope the will find a solution soon, because the mailpoet plugin used to work like a dream. If they cant find a solution then i have to go through the hassle by using a newsletter provider outside wordpress.

I have had the same issue since WP 4.3 .

I have seen before that setting the value “0” to “can_compress_scripts” in the MySQL table “prefix_options” have solved similar 404 errors for other plugins, but it didn’t this time.

I still get wp-admin/admin-ajax.php 404 (Not Found)
with: prototype.js?ver=2.6.16:1528 POST https://(removed)/wp-admin/admin-ajax.php 404 (Not Found)

PS: In Firefox it actuall shows the message “Saving”. But it doesn’t save. In Chrome that message is not shown at all

Do you developers replicate the issue, or does this work ok on another servers?

I’ll have to look for another plugin. = /

Guys, we already fixed this issue, and we are very close to release a new version soon. We are truly sorry it took us so long, but we used this opportunity to fix several other problems that were showing up lately.

That is good news.

Is there an expected release date for the new version?

or is there a beta version that can be downloaded somewhere?
