Hi
I have same problem.
framework Installed -> working with rt_quasar_j15 allright -> try to installing panacea no answer from the server. returning to blank page.
I think it not might be problem of the server.
Sometimes looks like its installed, but clicking on in the template manager i get white screen again.
I tried installing to the same domain from another pc.
:shock:
under > help > system info > php information i can see that your memory_limit is set to 16M, it should be at least 32M but something like 64M would be even better.
