Update CMSimple 4 to 5

An update from CMSimple 4 to CMSimple 5 is nothing more than an update from a CMSimple 4 version to a higher CMSimple 4 version. After the update, CMSimple continues to run in CMSimple 4 mode, as before.

From CMSimple 5.11 there is no longer a separate update package. The normal download of CMSimple 5.11 can be used as an update. You simply can copy (upload) the unpacked download over the existing installation of CMSimple 4 or 5.

Before you update a CMSimple Installation, you should make a backup of the whole installation on your PC.

After the successful update, you can decide whether the page should continue to be operated in CMSimple 4 mode or whether the content should be converted to h1only_pagesplit (CMSimple 5 mode).

If you decide to convert, please create a backup of content.php and pagedata.php again and save it.

You start the conversion by using the following configuration option:

Settings => CMS => Use => H1only_pagesplitting:

Set it to true and follow the further instructions of CMSimple 5.
