Hi Seb,
Unfortunately just replacing these two directories does not work. The
logs do not offer me any clue either. It could be that the changes have
made my web-app incompatible with the current one? Have there been
changes to to the javascript files in the example projects as well?
I have also recompiled paraview, just in case, but still does not work
with my app. By the way, I am unable to find the OSMesa options, as well
as the PARAVIEW_ENABLE_WEB in ccmake. Have they been deprecated?
Kind Regards,
Bogdan
