Before you begin:
1) Backup all files.
2) Backup your database.
3) rename the following files
- include/inc_conf/conf.inc.php -> _conf.inc.php
- include/inc_conf/conf.pagelayout.inc.php -> _conf.pagelayout.inc.php
- include/inc_conf/conf.template_default.inc.php -> _conf.template_default.inc.php
- include/inc_conf/conf.rss.inc.php -> _conf.rss.inc.php
- phpwcms_template/inc_css/frontend.css -> _frontend.css
- phpwcms_template/inc_css/print_layout.css -> _print_layout.css
4) be sure not to overwrite or replace
- content/images
- phpwcms_tmp and supdires there
5) Update all files with new from core package
6) Upgrade database:
- setup/upgrade.php should be enough
7) Extend your _conf.inc.php with additional or changed values from distribution conf.inc.php
rename all of your _***-files to system standard.
9) check your db if table phpwcms_pagelayout exists
10) check db table phpwcms_articlecat for field acat_ssl, acat_regonly
11) Login
12) create new pagelayout based on your old pagelayout settings
13) define pagelayout in templates
14) Delete setup directory
Should work
