@collectiveaccess I have re-installed Providence 1.7 schema 143 to make sure I have the latest viewer configuration. I also used caUtils to reprocess my image folder. In the media_display.config the default image viewer is set to Tileviewer, and the pdf viewer is set to Mirador. I still cannot see anything in the viewer when trying to view the pdf doc (1 page). Just see the bottom bar with the download tools. any suggestions as to how to proceed would be appreciated. Also if iset preferences to use Browser plugin (Firefox Document viewer) I cannot see the pdf document.
