Updated, if I deactivate then the site comes back fine, and then as soon as I reactivate again the stie disapears.

I talked to the host and it is already set to 128 so that is not the problem.. any other ideas?

Hi, i had similar problem a few weeks ago but i think i found out my problem. I number the WP style sheet filename as i update it to prevent caching and had deleted the default style.css file while tidying up. When opening the WP Design page, the template preview will fail because it can't find the style sheet and WP disables the template, but there is no other template to use so the site goes blank, while the admin remains functional

When installing CForms the same check for style.css may be triggered and so the template is disabled. I have now got 9.3 running and it seems fine so it may have been a 9.2 issue but I think in my case it was the missing default style sheet. Check the Design page in WP to see if your template is ok if you get the blank site
