Hi Juanra,

Can you please provide me with your wp-admin, I will have a quick look to see what's going on.

Kind Regards

Hi Juanra,

It seems like your hosting server is throwing a 406 error.

I had a similar problem recently with this 406 Not Acceptable error occurring when trying to update permalinks in WordPress. I also had the same problem when submitting any changes to the editor, etc. Google Webmaster tools would yield the same result.

The solution is to disable the mod_security firewall within your .htaccess file.

My fix was to install a plugin called "WP Htaccess Editor" (free WP plugin), then update the .htaccess file to the following, between the "Begin WordPress" and "End WordPress" tags:

- https://wordpress.org/plugins/wp-htaccess-editor/

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Kind Regards

I've found what is causing the failure.

https://prnt.sc/qr6qol

Your server is running out of memory, I've also checked the settings on site health, you had low settings set for the maximum execution time and similar features.

I would recommend you to talk to your host providers and tell them to do the changes below.

PHP Recommendations

Memory Size: memory_limit = 256M
Script execution time: max_execution_time = 400
Number of input variables: max_input_vars = 4000

If you don’t have access to the php.ini file, you can add the following values in your .htaccess file:

php_value max_execution_time 400
php_value memory_limit 256M
php_value upload_max_filesize 10M

Be careful using these settings, some hosting companies don’t allow users to change php settings, if you experience any problem after making these changes, please revert these in your .htaccess file, using your FTP client.

Kind Regards

I'm really lost, I've been reading and checking why this can happen.

Please check on this article, they're saying that the modsecurity can cause this too.

Hi Juanra,

Glad to know, feel free to ask for anything you need.

Kind Regards

Hi Juanrane,

Unfortunately I am not able to access the website, it says 403 forbidden access. https://prnt.sc/qtvt9q

How to place it on pages?

Go to the setting of the slider you want to display in your page and grab its shortcode. http://prntscr.com/n7bsr1

Edit the page with Elementor and place a shortcode element, inside that enter the shortcode of the slider. http://prntscr.com/n7bu3z

Feel free to ask for anything you need.

Kind Regards
