None of the forums have been used yet as the previous VB version was deliberately allowed to go dormant for a while. Have only used new additional forums as tests although I just posted one message on my managers forum tonight that's all.
I went through all the forums giving them nice clear one word URL endings.
But now I can't open any of them frontend.
I know it says:
Note that once specified, changing this value will cause URLs to be broken.
But since the import I never specified anything in that box up to now.
Can I not use that URL ending option?
