Blocks

Hi,

I have configured the Global Search block in Moodle 1.9.9 as per the instructions on the Moodle wiki. I have installed xpdf, doctotext, and antiword and given the files executable permissions to all users. (installed in usr/bin on CentOS) I have updated the paths in the Global Search admin block panel s such:

Path to command pdftotext
/usr/bin/pdftotext -enc UTF-8 -eol unix -q

Path to command doctotext:
/usr/bin/doctotext

Environment setting for the MSWord converter:
ANTIWORDHOME=/user/bin/antiword

Still, running any kind of search returns a blank page, which i assume is a safe mode PHP error. However, how can I diagnose what is going wrong? Is this a known issue and is there a solution/workaround to getting global search working when this happens?

Thank you!
