Preparing the Database for Installation

CREATE DATABASE db_name CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci;	

4.2. File Permissions

Change the permissions on the following files and directories to be writable

touch config/config.php
chmod 666 config/config.php

chmod 0755 _cache/config/ _cache/feed/ _cache/page/ _cache/query/ _cache/session/ _cache/template/ file/backup/ file/global/ file/perpage/ file/thumb/ xml/

chmod 0660 config/lock config/lock_ap sitemap.xml

reset after installation / upgrade
chmod 644 config/config.php

4.3. Path for session values

Check if the provided path for CACHE_SESSION_DIR is correct. The default value is /tmp but may vary in your environment.
Furthermore you may want to change this to a custom folder for the application (e.g. _cache/session) .


const CACHE_SESSION_DIR				= '/tmp';	

5. Admin panel

  • to login define the recovery_password in the config.php file first
    1. call the {{admin_recovery}} action as Admin and generate the password hash for your recovery_password
    2. add the password hash: 'recovery_password' => 'add hash here',
  • Don't forget to delete the _cache/config/config.php afterwards.
  • you must be logged in as member of the Admin group in the first place to access the admin panel
  • call yourwiki/admin.php
  • enter your recovery_password

If your Admin panel gets locked reset config/lock_ap from 1 to 0

6. Themes

If you want to keep your layout, you have to use a program like Meld or WinMerge to merge your CSS and other theme files with the new files in the folder wacko/theme/default.

You can write or adapt your theme also without using the template engine.

7. Backwards Compatibility

We dropped compatibility code for older PHP and MySQL versions. R6.0 requires at least PHP 7.3 and MySQL 5.7. To use WackoWiki with older PHP or MySQL versions, use the older branch of 5.5.x releases, which you can find on the download page.

8. Known Issues

All known issues are tracked in our Bug Tracker.

  1. MySQL 8: Remove the NO_AUTO_CREATE_USER in your constants.php, e.g.

    Otherwise it will throw a Fatal error: Uncaught mysqli_sql_exception: Variable 'sql_mode' can't be set to the value of 'NO_AUTO_CREATE_USER' in /setup/install-database.php:180
  2. Session duration issue - FIXED partially
  3. WikiEdit Autocomplete selection ain't working (help needed)
  4. Missing route cases (needs fix)
    1. CSS files in RECOVERY mode
