Wp-admin/admin-AJAX 403 forbidden

What I could suggest is to purge the cache and check for the permissions applied to cached files as well. Note that disabling the W3 total cache plugin does not delete the cached files., Your question has been posted! Share it with others to increase its visibility and to get it answered quickly. ,As the cloud firewall filters based on source IP addresses: Would it be possible for an attacker to create packets that have a spoofed source IP address and thus break through the firewall? I mean, assuming the attacker knew any whitelisted source. file permission changed

In this case maybe you have some special rules in your .htaccess file or your Apache virtual host, I would suggest trying with the default WordPress .htaccess rules and see how it goes:

# BEGIN WordPress RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond % !-f RewriteCond % !-d RewriteRule . /index.php [L] # END WordPress 

Another thing that might be causing the problem is an Apache module like mod-evasive for example. Could you run the following and check for any special modules like mod-security and mod-evasive :

Also make sure to check your Apache error log for more information:

tail -100 /var/log/apache2/error.log

The topic ‘admin-ajax.php 403 after installing the plugin’ is closed to new replies.,“request forbidden” error prevented the request from completing as expected. The server returned a 403 status code, indicating that the server configuration is prohibiting this request. This could be due to a plugin/theme conflict or a server configuration issue. Please try refreshing the page and trying again. If the request continues to fail, you may have to alter plugin settings or server configuration that could account for this AJAX request being blocked.”,I tried to deactivate the plugin but still have the same issue.,Thank you for your reply, The issue is that when I try to change anything from the setting of the plugins I got error too, so I cannot change anything there.

You can temporarily disable all iTSec plugin modules by (properly) adding the line below to the wp-config.php file:

define('ITSEC_DISABLE_MODULES', true);

I think it has now caused a new error after that change (attached) my images arent loading on most of my subsites! I’ve reenabled 1 and 2 with no luck.,@ Living Miracles – I don’t see anything in BPS Pro 12.8 that was updated/changed/etc. that would start causing this problem. So that is probably just coincidental and something else changed somewhere else. In any case, send me a WordPress Administrator login to this site so I can figure out what is causing the problem.,/files/folders/ is in my root wordpress folder – I am running a multisite installation of wordpress. I’ll check the other plugs or themes,@ Living Miracles – Go to your BPS Security Log page and post any Security Log entries for this 403 error so I can see what is being blocked.

# admin-ajax.php & post.php skip/bypass rule RewriteCond % (admin-ajax\.php) [NC] RewriteRule . - [S=2]

403 Forbidden – You don’t have permission to access /wp-admin/admin-ajax.php on this server

403 Forbidden – You don’t have permission to access /wp-admin/admin-ajax.php on this server

When I try to make a backup of my wordpress website through plugin I recieve the following error:

“403 Forbidden – You don’t have permission to access /wp-admin/admin-ajax.php on this server.”

This error also appears sometimes during installation of plugins.

# Begin WordPress RewriteEngine On RewriteBase / RewriteRule ^index.php$ - [L] RewriteCond % !-f RewriteCond % !-d RewriteRule . /index.php [L] # END WordPress 

inside /wordpress my entire wordpress website exists as:

-/wordpress -/wp-admin -/wp-content -/.htaccess 

Things I’ve tried:

-Used different plugins for backup (1 Updraft, 2 Duplicator) both show the same error.

-Change file permissions from ftp client.

Set 755 permission to wp-admin, wp-includes, wp-content directories

Set 644 to all files inside the directories and 755 to all the sub-folders.

-I even changed the folder permission of /wp-admin to 755 and admin-ajax.php to 777 but still getting the same error

-Made modification in .htaccess file as follows:

# BEGIN WordPress Order Deny,Allow Deny from all Allow from all RewriteEngine On RewriteBase / RewriteRule ^index.php$ - [L] RewriteCond % !-f RewriteCond % !-d RewriteRule . /index.php [L] # END WordPress 

-Disabled all plugins and enabled only the backup creating plugins, same error.

-Made a temporary 301 redirect in .htaccess file to be sure I was working on the right .htaccess file

-Disabled “Wordfence security” plugin

WordPress admin ajax 403 Forbidden issue fix

As a new update when you try to do this action it gives you an option to whitelist the action in question. Something like this.

So it solves this issue for the current user.

Old (outdated ?) story

I am using popular Newspaper theme on few of my websites. While editing theme settings from admin end it suddenly stopped saving theme settings. I tried different thing including inspect element and hence found this in the console. (see admin ajax 403 forbidden message)

Next step was to find what caused it

After a good amount of debugging, which included disabling all WordPress plugins and enabling them one by one, I discovered it was Wordfence Security plugin which as a measure to prevent XSS attacks blocked requests sent to admin-ajax.php as they (requests) contained javascript code which I saved to save my Google Adsense code. See Live Traffic log screen from Wordfence Security as below:

What was the Work-around?

Is there a permanent or more smarter solution? I don’t know. Disable Wordfence Security. NO, not at all!

However here is what I did in order to fix it for me. Look at the image below:

So everytime you wanted to edit theme options, just add your current IP address into this fields. If you have got static IP you could add it permanently and forgot it until your IP is changed. However if you have got dynamic IP like me, add it everytime you want to edit something in your theme including adsense ad code etc. I think if you dont have any javascript code block in your theme settings you may not be wanting to do anything silly such as this or infact you may not be looking at this post at all! 🙂
