Hi,
I once had this issue too, where the styles did not appear at all. For me it helped to clear the browser cache and clearing the session. Once I logged in again and did a complete page reload, it worked again...
Currently I'm experiencing another issue related to custom CKEditor styles:
I have two textarea fields with CKEditor as inputfield type and both have the JS styleset option set (to the same value).
When editing a page which uses this template, the custom styleset only works for the first CKEditor instance. The following ones only show the default style options.
Changing the order of fields in the template won't work, so it's really related to the order in which the fields are added in the template. It's without exception only the first field where it works properly...
Can anyone reproduce this issue? I'm using PW 3.0.21.
Edit: Hm... just upgraded to PW 3.0.23 and now everything works properly
Cheers
Alex
