<p class="MsoNormal">I have been trying to set up a ParaViewWeb server on my CentOS 6 machine to run Visualizer. I have gotten to a point where the UI loads correctly but remote rendering only displays a black screen. Not even the axes in the bottom left are
displayed. However, if I switch to local rendering mode it works as normal. There are no errors at all in the Apache logs and the session log starts fine but after the twisted server startup and the lines filled with plus signs, I get the lines:<u></u><u></u></p>
