I'm working with WordPress 4.9.6 and i have a problem for 2 days... I can't save any post if there is the html tag inside with editor or not, i mean &lt;html&gt; or <html>. If i try to save, i have an error page not found.

I can write other html tags with no problem, it's only the html one wich give me difficulties...

I have tried :

  • disable every plugins
  • Save my permalink again...
  • Change the version of PHP (i work with O2Switch with PHP 7.2)

Can anyone help me ?
