Blank Page after Activation, more

Out of the blue, I was unable to login in. The login page presented itself, I put in name and password, then the next page displayed was blank, it did not load the dashboard.

After reading some fixes, I renamed the plugins directory to pluginsxx. I was then able to login as normal, but all of my plugins were deactivated. Renaming the the plugins directory, I was still able to login again.

Now, the problem I am having is this white page in a lot of places. Specifically, when I re-activate a plugin, it goes to a blank page, although the action happened. I have to find my way back to the dashboard and check the plugin. It shows it was activated.

I deleted a Page, and the same result – blank page.

It’s like the next page to load, does not do it – very much like the original problem of logging in and then the dashboard would not load.

In the 3 examples below, the last action “wpnounce” shows. I am not exactly sure what that does, but that is the common thread.

Also, clicking on “Log Out” gives me the url below, but does NOT log me out.

Does anyone have a solution? From the end user, everything looks fine.
