Thanks, Kyle. I configured memcached on all instances a few weeks back. Restarting cleared the error message. However, continuing with your instructions on GitHub… - Uploaded v2.0 and configured the plugin through “Report Plugins” - On the server itself, the CoverFlow files are present in the instance’s directory (/var/lib/koha/library1/plugins/Koha/Plugin/Com/ByWaterSolutions/CoverFlow/coverflow.pl, etc.) - Created a local report that successfully returns a handful of records with biblionumber, isbn & title - Followed the remainder of the configuration as described in the document (https://github.com/bywatersolutions/koha-plugin-coverflow) substituting the new report’s number - Restarted both apache2 and memcached…just to be on the safe side - The opac shows nothing more than “Loading…” Looking at apache2/other_vhosts_access.log, it appears a 404 error is being generated when the page attempts to hit jquery.flipster.min.js … "GET /plugin/Koha/Plugin/Com/ByWaterSolutions/CoverFlow/jquery-flipster/src/js/jquery.flipster.min.js?_=1454006509306 HTTP/1.1" 404 … gcb Are you running memcached? If so you'll want to restart that: sudo /etc/init.d/memcached restart Kyle http://www.kylehall.info ByWater Solutions ( http://bywatersolutions.com ) Meadville Public Library ( http://www.meadvillelibrary.org ) Crawford County Federated Library System ( http://www.ccfls.org ) Mill Run Technology Solutions ( http://millruntech.com )
