I experiment the same problem ( except blank occurs from the opening of the existing documents and I did not install any script )
I ve been using Scribus for some days now, was great ! Til I opened my document and ... all the pages are white !
Same if I switch to @View mode@
When I print, it s correct, all content are there
The problem is I need to keep editing it ...
I use Scribus 1,5,2 ( latest version)
I m on the latest Apple OS (Sierra )
I don t use any ghost script
All existing documents I open have the same issue
I already tried to restart Scribus a few times, as my mac. With no more results
Thanks in advance community !
