Ciao Piero,

Make a simple test, make "Cassiopeia" your default template, clear Joomla cache and preview those pages again.

If no error message , you have to contact with Flex template developer.

If still error message but with different desin:

1. Respond to my questions below (1 & 2)
2. si, condividere l'accesso

BTW

1. Are you able to open those pages in SPPB back-end editor?
2. Are they have published "green" status on the list?

I put cassiopeia as the default template. Still it doesn't work, but... I've a different style for flex template in my home page. When I change it (and do not assign flex home template to my home page, so that the default template for my home page is cassiopeia too, then PB links do work...

Are you able to open those pages in SPPB back-end editor? Are they have published "green" status on the list?

Yes, and yes too.

If pages are displayed on "Cassiopeia" view - but not on Flex template - write to Aplikko support.

Probably view overrides from that template, as always, makes problem.

Hello again, I changed the default template to shaper, but I keep having problems with PB displaying. When I try to preview it always (it seems) returns to the home page view.

Thank you

Piero
