PDF conversion broken by multicolumn formatting: "Article could not be rendered"
Closed, ResolvedPublic


Author: nrp

This is my first bug report so forgive me if I screw it up.

We received an e-mail at OTRS (ticket # 2013030410006626) about a problem with the PDF conversion of the Stabat Mater article (

The error as reported is:

"I've tried to get the PDF of 'Stabat Mater' over the past week. It does not form into a proper PDF with the proper layout - this is the first time I have come across this issue.

The message at the top of the PDF reads: "WARNING: Article could not be rendered - ouputting plain text. Potential causes of the problem are: (a) a bug in the pdf-writer software (b) problematic Mediawiki markup (c) table is too wide" --- this one on attempt dated 04Mar13"

After asking at VPT, another user responded that the culprit is the multi-column formatting in the Text section. I copied the article to a user subpage without the multi-column formatting ( and asked the user who reported the problem to see if it now worked. The user reported back that it does indeed convert to PDF without that formatting.

Is this still going to be an issue with the new Proton service?

Both seem fixed now with Proton PDF rendering. Book rendering not taken into consideration.
