@queryluke i updated the xsl and css for the transcription viewer, but i'm getting an internal server error when i try out some xml. the server can't seem to read xsl/transcription.xsl.

from the log:

I tried to debug this and the issue are deeper than a pathing problem. You can fix the pathing problem by changing run.py line 26 to:

xslt_xml = etree.parse(app.open_resource("xsl/transcription.xsl"))

I tried this on dev, but the XSLT transformation is timing out. Resulting in:

[Wed Feb 01 17:16:49 2017] [error] [client 152.23.152.73] Premature end of script headers: dtp-qa.wsgi, referer: http://dtp-qa.lib.unc.edu/

The offending line seems to be line 27, when etree parses the file. This only seems to be a problem on the server, so it might be a python26/27 issue. Either way, I'm not sure how much time I'll be able to devote to this over the next couple of weeks.

The semi-good news is that everything works locally. Do the people who need to use this application use macs?

[ghost]

yeah, i think they all use macs.

bringing @joeafletch into this one

[queryluke]

@joeafletch, see if the instructions I've provided in the readme work for you

[ericloy]

We all use Macs up in Rochester FYI.

@queryluke I got "error: can't create or remove files in install directory" when I tried to follow the readme instructions. But I'm a novice when it comes to using terminal so there may be something I need to do that @ba001 can help me with.

added 'sudo' to the instructions. should be good to go
