JoshPet said:Make sure you add the options into the config file and define them (see the first part of the instructions).
It uses 2 config variables to determine maximum width and if anonymous users can see them inline - if you don't add the options to the config file - then nothing appears. [/]
Did as you said from the beginning but it didn't work.
I always read instructions very carefully.

I then took the old showthreaded.php and showflat.php files from my 6.2.3 backup, copied the modified stuff out of it and pasted it into the new 6.3 files. Voila...it worked.
I only hope that I didn't mess up something.
Unfortunately I didn't have the time to make a comparison between the files but if you want me to (I don't know if Infopop allows sending files from UBBThreads), I can send you my showthreaded.php and showflat.php files via eMail.
Thanks for trying to help.
