404 Wordpress Authentication Issue


byDSGN

Hello! I’m trying to connect my WordPress to Zapier. But it’s giving me a 404 authentication error. I’m running the most current versions of WordPress and the Zapier plugin. And the plugin is installed and active. I’ve tried everything I could find that was recommended to other folks for this problem (making permalinks post name, reinstalling the plugin, and making sure xml-rpc is enabled. Please help!

Hi @byDSGN!

Wordpress connections are tricky because so many factors play a role in them. 

 

If you haven’t already done so, I recommend going through this help doc: Common problems with WordPress

If you’ve already tried that and/or it doesn’t solve the issue, I recommend going to the Support Team using the Get Help form. They’re able to look at your Zaps logs and can provide more insight into what’s happening. When you message them, be sure to include details of everything you’ve tried so far, so they don’t ask you to try them again. 

 

Thanks!

Hi @Brem , I am also having the same issue. I have looked at all the support pages and documentation, and still can’t seem to fix the issue.

Hi @10slindsay,

I’m jumping in to see if I can help!

Before we dig in, could you please confirm that the Zapier WordPress plugin is installed on your website and that you have admin permissions on your WordPress account? This is required to connect WordPress to your Zapier account.

I also checked our notes and found a similar issue with another user. They discovered the hosting provider was blocking traffic from Amazon AWS, which Zapier uses. Some changes in the firewall on their end did the trick.
 
Also, here are a few other things to remember: 

  1. Make sure to reconnect the account and make sure to include the WWW  part of the URL
  2. If that doesn't work, the next step would be to temporarily deactivate any security plugins that could interfere with us trying to connect.
  3. Also, is it possible to check to ensure that the WordPress Plugin is activated in the Plugin Dashboard? https://help.zapier.com/hc/en-us/articles/8496101767309

Does that point you in the right direction? Please keep us posted! 😊


Hi, 

Has there been any follow up on this topic? I have been trying to connect a Wordpress account multiple times, looked through all the community help posts and did every suggestion, and nothing seems to be working. This is the error I get:
 

 

Could you please let me know what are the other possible fixes? I tried the following (probably even more)

  • Disabling all the plugins
  • Activating the Zapier plugin & have admin access
  • Added another account Zapier as a user
  • Tried downgrading WP version to the one that was last tested with Zapier
  • Etc (can’t remember all but basically all that have been mentioning on this blog).

It’s really important for me to get this integration for my client who uses WP a lot. Thus, it would be great to get some help on this, since so far nothing seemed to solve the issue for me :)

 

Thanks in advance!

Hi @OptimAIze Labs,

I’m so sorry to hear about the trouble connecting WordPress with Zapier.

Before we dig deeper into this, could you please confirm if you have the WordFence plugin installed? If so, could you please try disabling the plugin? 

If it still doesn't work, could you please check if any settings in WordFence might be conflicting with the Zapier plugin.

Please keep me posted!

Has any other resolutions been found?  I’m running on wpengine host and this one site still gives me this error. What is strange - I have 2 other duplicate sites with the same plugins and authentication is working.

Any ideas?

Hi there @pjgary,

The issue could be caused if a Default “Plain” permalinks are being used - e.g. https://yourwebsite.com/p=123

Could you please try switching WordPress to use a different permalink structure such as Post name. When switched, the authentication works without an issue.

Hopefully, this helps.

permalinks are based on post tag - that was not the issue.  Host company is trying to reset site permissions - will update thread once I see what happens

Hi @pjgary,

 

Keep us posted on this one. We would like to know if resetting the site permission will fix the issue.

This is driving me mad. I’ve installed the plugin, have admin rights, changed permalinks between postname and plain and have non of the blogging plugins installed. Why can I not get this connected? It’s either 403 or 404 depending on the Permalink structure.

 

Thank you

Anja

Hi ​@Anja80,

 

A 403 error indicates a lack of authorization, while a 404 error means the server can't find the requested resource. To troubleshoot, check the plugin settings, ensure API keys and URLs are correct, verify the .htaccess file permissions, turn off conflicting plugins, and confirm WordPress is up-to-date. If the issue persists, contacting the plugin developer for support may help. Providing additional error details can also aid in finding a solution.

Dear JammerS,

 

How do I check the plugin settings? I can only activate and deactivate - no other options.

 

All I have done is:

Download plugin and activate

In Zapier, connect to Wordpress, enter my details (they have admin rights).

That’s it. There are no conflicting plugins and Wordpress is up-to-date. Tried on another Wordpress page and had some problems. Have no idea what else to do.

 

Thank you,

Anja

Hi ​@Anja80,

 

The settings for the Zapier WordPress plugin should be available in your WordPress dashboard. Here's how you can access them:

  1. Log in to your WordPress dashboard.
  2. Go to 'Plugins' on the left-hand side menu.
  3. Find the 'Zapier' plugin in your list of installed plugins.
  4. Click on 'Settings' under the plugin name.

If you don't see the 'Settings' option, it might be a problem with the plugin installation. You could try deactivating and deleting the plugin and then reinstalling it. When connecting Zapier to WordPress, make sure you're using the correct URL for your website and that you're using an account with Administrator permissions.
