Hi,
I have
copied the nav:side-en to nav:side-cz
downloaded the flag of Czech Republik to change to gif ( 20x13)
uploaded the flag as cz:gif to include:languages , and -horizontal
changed the source of this flag sources to show cz-flag
copied en:_template to cz:_template ( with the include of all this flag dependent sources)
AND:
copied the start of cs:start ( still exist!) to cz:start and detected that the page names where wrong !
REMINDER pagename MUST be in English, the same for all languages
example:1 fr:pagename de:pagename tr:pagename
EXAMPLE2: internal link - part 1 = the pagename in english, part2 = description/title in other languages ( here german )
[[[cz:What Is A License ? | Was ist eine Lizenz?]]] _
[[[cz:Find A Page | Finden einer Seite]]] _
Now your changes should work!
PLEASE: only on cz:start!
