Title: Cannot Authenticate Last modified: August 30, 2016 --- # Cannot Authenticate * Resolved [derricka](https://wordpress.org/support/users/derricka/) * (@derricka) * [10 years, 10 months ago](https://wordpress.org/support/topic/cannot-authenticate/) * I keep getting an authentication error trying to use the plugin. My username is correct, password is correct and API key is correct. I also verified in my Pardot account that IP security is disabled so I don’t think I should need to worry about whitelisting any IP’s. * I also have a wordpress install running an older version of WordPress that is experiencing the same authentication error so I don’t think it’s related to the WP version I’m using. * How can this be fixed? * Thanks, Derrick * [https://wordpress.org/plugins/pardot/](https://wordpress.org/plugins/pardot/) Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 10 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221700) * Hey Derrick, * Have you been able to authenticate with the Pardot plugin previously on this server? It’s often related to a configuration issue. * [iconiq](https://wordpress.org/support/users/iconiq/) * (@iconiq) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221980) * I also can’t authenticate the WP plugin even though the credentials and API key are accurate. I keep getting this error message with no explanation as to what is wrong “Cannot authenticate. Please check the fields below and click “Save Settings” again.” Please help! * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221981) * Hey [@iconiq](https://wordpress.org/support/users/iconiq/), * Like I mentioned, it’s often related to a configuration issue. If you’re certain the credentials are correct, two things to check: - If your Pardot account is set up to only allow access from certain IP addresses, make sure your server’s is one of them. - Contact your web host to make sure that the proper things are turned on to make external API calls. * [iconiq](https://wordpress.org/support/users/iconiq/) * (@iconiq) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221982) * Hi Cliff, IP whitelisting is diabled and I’m running WP on localhost. What else could prevent me from authenticating? I really need this resolved as we’re fast approaching a deadline. Thanks. * Connie * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221983) * Connie, * I understand the urgency, but there’s not much I can do in this case. Everything’s dependent on the server configuration (even a local one). * Authentication is working for others, so the best thing you can do now is disable all the other plugins and turn on the default theme. See if it works then. If it does, it’s a plugin/theme conflict. Otherwise, it’s likely to be a configuration issue with your localhost. * At least one of the the libraries that can be used to make the API call is [cURL](http://php.net/manual/en/book.curl.php). Make sure that’s installed for PHP. * [iconiq](https://wordpress.org/support/users/iconiq/) * (@iconiq) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221984) * Cliff, cURL is installed and I’ve turned off all other plugins and it’s still not working. What could be the configuration issues with my localhost? I’m completely blocked by this. * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221985) * What sort of localhost are you using? * [iconiq](https://wordpress.org/support/users/iconiq/) * (@iconiq) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221986) * I’m using Apache on a Mac, if that matters. * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221987) * That’s not quite enough for me to help, unfortunately. Can you possibly try on a public server? * [iconiq](https://wordpress.org/support/users/iconiq/) * (@iconiq) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221988) * So the issue was something to do with my localhost configuration. I migrated the site to another server and the authentication worked. *shrugs* * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [10 years, 7 months ago](https://wordpress.org/support/topic/cannot-authenticate/#post-6221989) * Sorry for the trouble, but that’s great to hear!
