Hey Jo, Welcome back to

You already did everything which might figure out the issue if the issue was from Wordpress so I suggest if you checked the mod_security configuration & you can contact the support of your hosting provider because I believe that this is a server error because of security, because you mentioned that this issue happen especially if there is a lot of HTML inside the page, So please check the security configuration on your server 

Good Luck!
