MailChimp API stopped working

Hello
I have set s2Member to display a check box on the registration form that will sign users up to a mail list in MailChimp on registration.It was working fine a few days ago.

BEtween the time it was working and now, when it is not working, I upgraded the main hosting account for this domain from a shared hosting account to a dedicated IP address. The MX records on this domain also changed. However, all other mail forms work on this domain and other domains on this main domain also have s2Member and the API integration is working for those domains.

Any idea what might be causing the MailChimp API ont his domain to stop working and how can I fix it?

No, don’t know…

Could you check if you have logging enabled? [hilite path]Dashboard -› s2Member® -› PayPal® Options -› Account Details -› Logging[/hilite] (it’s logging in general, even if it’s in the PayPal options page)

Enable it and to a test registration, then check if a log was created for MailChimp and post here the entry, please.

Did you change anything other than the server? Like updating other plugins?

Ah, and could upload this to your WP directory and open it in your browser, please? http://www.s2member.com/r/server-check-tool/

Thanks. :)

PayPal logs were NOT previous enabled but are now
Logs were recording tests earlier this morning but seem to have stopped logging subsequent tests.

While the above code seems to indicate that the last logged attempt worked, subsequent tests have NOT worked and are not being logged. Server passed php check on all points

As far as updating plugins…. I did upgrade s2Member to latest version as well as the Pro module

If nothing is being logged since this morning, even though you’re still doing tests and logging is still enabled, that would indicate something else is going on, i.e., a permissions issue in writing to the log file or communications issues between your server and PayPal.

I would try disabling s2Member and then reactivating it (make sure Deactivation Safeguards are enabled in Dashboard -› s2Member® -› General Options -› Deactivation Safeguards). I would also try disabling all other WordPress plugins and testing again to rule out a conflict with another plugin.

If you recently changed servers, then keep in mind that changes to the DNS system were made as well. Servers and routers on the internet cache (i.e., keep a copy) of the DNS information and only update that cache every 24-72 hours. It’s possible that MailChimp’s servers, or a router in between your server and MailChimp, have an old DNS cache and it’s trying to communicate with the IP address associated with the old server.

However, if you’re not even getting anything logged in the s2Member logs, then something is wrong “closer to home”, i.e., on the server itself, so I’d start there.

This is clearly going to require a full on investigation and extensive testing to nail down the issue. I am going to have to clone the site and create a test envrionment (which I should already have).

It seems to me that this might be the most likely scenario “It’s possible that MailChimp’s servers, or a router in between your server and MailChimp, have an old DNS cache and it’s trying to communicate with the IP address associated with the old server.”

Thank you for the response. Guess I’ll just have to put on my CSI hat…… ;)

Glad I could help! Let us know if you have any other questions. :)
