Login WordPress => MailChimp fails

(@behemothkind)

WordPress: 3.9.1
MailChimp List Subscribe Form: 1.4.1

I try to login to MailChimp via the WordPress plug-in but I get an error message:

POST to http://www.myDomain.com/index.php?mcsf_action=authorized&salt=2b48aba70f7fb3945fa7a20ad731a356&user_id=1 failed with 500: <!DOCTYPE html> <!-- Ticket #11289, IE bug fix: always pad the error page with enough characters such that it is greater than 512 bytes, even after gzip compression abcdefghijklmnopqrstuvwxyz1234567890aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz11223344556677889900abacbcbdcdcededfefegfgfhghgihihjijikjkjlklkmlmlnmnmononpopoqpqprqrqsrsrtstsubcbcdcdedefefgfabcadefbghicjkldmnoepqrfstugvwxhyz1i234j567k890laabmbccnddeoeffpgghqhiirjjksklltmmnunoovppqwqrrxsstytuuzvvw0wxx1yyz2z113223434455666777889890091abc2def3ghi4jkl5mno6pqr7stu8vwx9yz11aab2bcc3dd4ee5ff6gg7hh8ii9j0jk1kl2lmm3nnoo4p5pq6qrr7ss8tt9uuvv0wwx1x2yyzz13aba4cbcb5dcdc6dedfef8egf9gfh0ghg1ihi2hji3jik4jkj5lkl6kml7mln8mnm9ono --> <html xmlns="http://www.w3.org/1999/xhtml" lang="en-US"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>WordPress › Error</title> <style type="text/css"> html { background: #f1f1f1; } body { background: #fff; color: #444; font-family: "Open Sans", sans-serif; margin: 2em auto; padding: 1em 2em; max-width: 700px; -webkit-box-shadow: 0 1px 3px rgba(0,0,0,0.13); box-shadow: 0 1px 3px rgba(0,0,0,0.13); } h1 { border-bottom: 1px solid #dadada; clear: both; color: #666; font: 24px "Open Sans", sans-serif; margin: 30px 0 0 0; padding: 0; padding-bottom: 7px; } #error-page { margin-top: 50px; } #error-page p { font-size: 14px; line-height: 1.5; margin: 25px 0 20px; } #error-page code { font-family: Consolas, Monaco, monospace; } ul li { margin-bottom: 10px; font-size: 14px ; } a { color: #21759B; text-decoration: none; } a:hover { color: #D54E21; } .button { background: #f7f7f7; border: 1px solid #cccccc; color: #555; display: inline-block; text-decoration: none; font-size: 13px; line-height: 26px; height: 28px; margin: 0; padding: 0 10px 1px; cursor: pointer; -webkit-border-radius: 3px; -webkit-appearance: none; border-radius: 3px; white-space: nowrap; -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; -webkit-box-shadow: inset 0 1px 0 #fff, 0 1px 0 rgba(0,0,0,.08); box-shadow: inset 0 1px 0 #fff, 0 1px 0 rgba(0,0,0,.08); vertical-align: top; } .button.button-large { height: 29px; line-height: 28px; padding: 0 12px; } .button:hover, .button:focus { background: #fafafa; border-color: #999; color: #222; } .button:focus { -webkit-box-shadow: 1px 1px 1px rgba(0,0,0,.2); box-shadow: 1px 1px 1px rgba(0,0,0,.2); } .button:active { background: #eee; border-color: #999; color: #333; -webkit-box-shadow: inset 0 2px 5px -3px rgba( 0, 0, 0, 0.5 ); box-shadow: inset 0 2px 5px -3px rgba( 0, 0, 0, 0.5 ); } </style> </head> <body id="error-page"> <p>Cheatin’ huh?</p></body> </html>

So MailChimp is failing with an http 500 response when it tries to access the file index.php?mcsf_action=authorized&salt=2b48aba70f7fb3945fa7a20ad731a356&user_id=1

What did I try:
1. Cleaning cache + cookies
2. Trying it on the latest FF and Chrome

Any ideas why this happens?

Many thanks,
B

Hi Behemothkind,

Thanks for hopping in the forum. Sometimes this error is caused by other plugins interfering with the connection. We’ve seen similar issues with wordpress firewalls and wp supercache if you have those installed.

You might want to try disabling all other plugins, then enabling them one at a time, then try to connect. This can help narrow down if a plugin is causing the issue.

If that doesn’t work, try uninstalling and installing the plugin. You might also want to check with your host to make sure there aren’t any restrictions on connections. They can whitelist this site and these ip addresses: 50.23.108.137 50.97.194.22 https://sopresto.socialize-this.com

This thread also has additional troubleshooting steps you can take: http://wordpress.org/support/topic/error-couldnt-connect-to-host?replies=23

Let us know if you have any other questions.

Hello mc_d,

Thank you for your answer, I appreciate your help.

I still can’t log-in but I gave my web host only one of the two IPs you listed here so now I send him the other as well and hope for the best.

My WP installation is very fresh and I have not many plug-ins:
Antispam Bee
Captcha
Google Analytics for WordPress
Limit Login Attempts
MailChimp
Page Links To
Shareaholic | share buttons, analytics, related content
WebRotate 360 Product Viewer for WordPress

On the face of it, I don’t think any of them interferes with the MailChimp plug-in.

I will wait for my web host to white list the two IPs and the URL and if this still doesn’t help I will deactivate all plug-ins and see if this helps.

Thank you for now,
B

Hey behemothkind,

Feel free to let us know if you end up continuing to see that issue, but that whitelisting *should* do the trick!

Hi mc_gabe,

I appreciate your help.

My support guy said: “…please disable mod_security for your domain name…”

And that did the trick!

Thanks for your help,
B
