+I can't add any attachment to my wiki. When I select file using "Browse"
+button and click "Upload Attachment", then `ikiwiki.cgi` file displays
+the error message like below:
+
+ Błąd: failed to get filehandle
+
+The same message I can see in the Apache log file. There is also

+ Use of uninitialized value in length at /usr/share/perl5/IkiWiki/Plugin/attachment.pm line 36.

I have backported Ikiwiki 2.52 and I need to add that plugin to
`add_plugins` variable in my `ikiwiki.setup` file (and rebuild
my wiki, of course) to see new upload buttons when I edit a page

Maybe should I enable attachment handling in different way?
