cPanel Request body no files data length is larger than the configured limit

On a WordPress website hosted on Cpanel server, when editing a page, i get 404 error. On checking ModSecurity logs, found the following

Message: Request body no files data length is larger than the configured limit (1048576).
Message: collection_store: Failed to access DBM file "/var/cpanel/secdatadir/serverok-session": Permission denied

To fix the error, edit the file

vi /etc/apache2/conf.d/modsec/modsec2.user.conf

In the file, add

SecRequestBodyNoFilesLimit 1548576

Restart Apache

systemctl restart httpd

If the above did not work, you can try increasing value of SecRequestBodyNoFilesLimit. When you change the value, don’t forget to restart Apache webserver.
