Install CMSimple 4

At first you should create a backup copy
of your old CMSimple installation
in a folder on your PC.

After that you should delete
Cookies and Browser Cache
in your browser.

Then you can start preparing for the update.

  1. Create a new folder in your local server environment or on your web server. This directory should not be named "cmsimple", to avoid confusion with the system folder of CMSimple.
  2. Install the latest version of CMSimple in this directory, as described in Installation.
  3. The folders 2author, 2lang, 2site und 2site2lang are copy templates and should not be uploaded to the webserver.
  4. On many web servers, you have to assign the necessary write permissions to some files and folders now.
  5. Delete the file ./content/pagedata.php

The pagedata.php from the download already contains data that does not fit for the contents of your old CMSimple installation. CMSimple will create a new pagedata.php.

If your old CMSimple installation already has a pagedata.php, overwrite the original pagedata.php with your pagedata.php.

Your new CMSimple installation is now prepared, for the transfer of the data (content.htm) from your old CMSimple installation.
