Radical Suggestion: Use Completely JSON in webpages/browsers. better than HTML

We are using Json in many "data presentation" tasks. Why would it not be the case for creating/displaying webpages ?
I make a Radical Suggestion: Use Completely JSON in webpages/browsers.
That is, a website should be presented in JSON (like named array), browser should interpret and show pages from these json data. This would speed up many development and parsing needs.. Many computer/processing/energy power may be saved.
- webservers (including interpreters like php/python) would be faster, bc preparing a webpage would be much faster.

Ehcp Version 18.04 first preview available...

We have prepared first preview version of Ehcp 18.04, which is for Ubuntu 18.04.
You can download and try/test it from http://ehcp.net/ehcp_1804.tgz

We have tested only basic functionality. Ehcp installs directly, ehcp login works, domain/ftp add works.
We did not test every detailed feature, please test yourself and share your test results with us via info@ehcp.net.

A fix for Ubuntu 16.04

With Ehcp 0.38.5 and later (on Ubuntu 16.04), init scripts in /etc/init.d may cause some apt update commands to fail. So, please move ehcp and ehcp_daemon.py that is in /etc/init.d to some other location, until this is fixed.
After this move, apt -f install command would fix the apt system.
