Title: Cannot authenticate error Last modified: September 27, 2016 --- # Cannot authenticate error * Resolved [wardy83](https://wordpress.org/support/users/wardy83/) * (@wardy83) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/) * Hi the plugin is working again now, but twice in the past two days and on other occasions prior, we have had a ‘Cannot authenticate’ error which has stopped all forms appearing on the website. * What is the reason for this and how can we be alerted (other than by our customers) when this happens to know how to fix it. * We are not using whitelisted IP’s and are using shared hosting. * Considering reverting back to iframe embedded code if this happens again, but its a big undertaking so hoping for some reassurance in this plugin. * Thanks.

Issue for us is because of broken creds. They becomes invalid or just missing without any activity, - This reply was modified 9 years, 8 months ago by [RCooLeR](https://wordpress.org/support/users/rcooler/). * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8235226) * [@wardy83](https://wordpress.org/support/users/wardy83/) Am I reading correctly that you can authenticate, but that it becomes un-authenticated without any action? * [@rcooler](https://wordpress.org/support/users/rcooler/) I see your existing thread, so let me help you there. * [fastasleep](https://wordpress.org/support/users/fastasleep/) * (@fastasleep) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8237405) * Same. (sorry, piggybacking on both threads so I can subscribe to replies on both— my client is freaking out about this). Thanks! * Thread Starter [wardy83](https://wordpress.org/support/users/wardy83/) * (@wardy83) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8238521) * [@cliffseal](https://wordpress.org/support/users/cliffseal/) Yes, that’s correct. I am able to re-authenticate by putting in the wrong password saving settings and then changing it back to the correct password and saving settings. * On my key forms I have reverted to the iframe method as this issue had a few people worried! * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8239336) * Try adding back the following at line 927 in `includes/pardot-settings-class. php` and then re-auth: * `$settings['password'] = self::pardot_encrypt( $settings['password'], 'pardot_key');` * That will mess up the formatting (possibly) in the settings area itself, but may be the part that’s causing the un-auth issue. * [fastasleep](https://wordpress.org/support/users/fastasleep/) * (@fastasleep) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8240351) * I’ve added that line to 927 and will keep an eye on it today. Hopefully that does it. * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8240359) * Great! I was able to replicate today and am looking at this as a release ASAP: [https://github.com/Pardot/pardot-for-wordpress/pull/12](https://github.com/Pardot/pardot-for-wordpress/pull/12) * Things have stayed auth’d for me today. If it continues, I’ll release. * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8255435) * This should be fixed as of 1.4.2. * Thread Starter [wardy83](https://wordpress.org/support/users/wardy83/) * (@wardy83) * [9 years, 8 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8255462) * SO far so good for me also – thanks for your efforts on this. Will let you know if I see any different. All the best. * [darlene22](https://wordpress.org/support/users/darlene22/) * (@darlene22) * [9 years, 4 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8651700) * I just installed v.1.4.2 of the Pardot plugin and still cannot authenticate. I tried adding the line of code to the includes/pardot-settings-class.php on line 927 as instructed and this didn’t help. I would have thought this wasn’t necessary in the latest version. But with or without the added code, I still cannot authenticate. I would appreciate your assistance. * Plugin Author [Cliff Seal](https://wordpress.org/support/users/cliffseal/) * (@cliffseal) * [9 years, 4 months ago](https://wordpress.org/support/topic/cannot-authenticate-error/#post-8660735) * [@darlene22](https://wordpress.org/support/users/darlene22/) That’s a different issue that may be more related to your individual setup. Can you please contact Pardot Support to walk through some options first? If you’re still having trouble, create a new support thread so I can help there.
