Summary0001067: White screen error during forms generation with partially installed system (test jig setup, fix attached)
DescriptionIf for any reason you don't have FPDF installed (for making PDF files) and you try to make a CAP form, you get white screen instead of correct error message.
Steps To ReproduceRemove (or omit) the files /usr/share/fpdf/ and /usr/share/ufpdf/

Click on "CAP Forms" and then any form eg A4 WoT Form

Blank page results.
Correct behaviour would be an error message

In a fully installed system, you get Save/View incoming PDF, per browser choice.
Additional InformationI'm documenting bugs which stop you setting up a test jig.

The log should help you find the correct solution, which is to install the appropriate FPDF variants

At least for test purposes you can do
 sudo apt-get install php-fpdf
 cd /usr/share/
 sudo ln -s fpdf ufpdf

Proper installation requires something like these
wget http://acko.net/files/ufpdf/ufpdf.zip
wget http://www.fpdf.org/download/japanese.zip
TagsNo tags attached.
