Ich habe alles installiert und es funktioniert auch. Allerdings erhalte ich die folgenden Meldungen und mein Englich langt nicht dafür (biite nicht lachen):
TROUBLESHOOTING
Do not use unless you know what you are doing! Please read descriptions to the buttons to check what they are doing exactly.
RE-INITIALIZE POWER FEATURES
use ONLY if something behaves strange, it might help in some cases
The button will do following steps automatically:
1) Unpublish core plugin and publish CW Multicats custom plugin for Page Navigation: see here:
Content - Page CW Multicats Navigation - ENABLED
Content - Page Navigation - DISABLED
2) Copy template override files for ISIS administration template to provide necessary functionality.
Restore Category Selection
Restore Category Selection will restore category ID(s) from
#__content table. This means that it will try to restore multiselection
from attribs where is backup stored even if CW Multicats are
uninstalled. If there is nothing found, for example if there hasnt been
anything stored yet for multicategories (fresh install of CW
Multicategories OR if Your CW Multicats version before update was lower
than 3.7.2.1, then it will load just primary category ID from
#__content.catid column.
Therefore use it carefully and is recommended to do database backup before updates.
Reset Articles Ordering
This will reset stored Multicategory Ordering - delete all articles ordering for multiple categories.
Bin für alle Tipps dankbar!
