we use Xwiki 11.10.2 and had CKEditor 1.39 installed. All worked fine so far.
Now we updated to CKEditor 1.64.6 and now the Styles in CKEditor are gone.
There is no Style in the Styles downdown.
Do you have any suggestions where to look for the reason?
To be precise, the long term support (LTS) is currently 13.10.9. https://www.xwiki.org/xwiki/bin/view/Download/ is kept up to date with the latest versions of each supported branches.
It’s advised to try to keep up to date with LTS if you want to have a stable and supported wiki instance.
