Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Ten theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
Currently, I can access the plugins only by ftp. When I try to log in, I get only a full screen of additional errors. Is there a way I can deactivate the plugins from outside the admin dashboard?
yes, by ftp.
Rename the plugins folder in wp-content to something else and make a new empty plugin folder
Thanks! And my apologies to esmi for responding before reading through the link esmi posted, which contained that information, too. I tried doing that and got the same screen of additional errors:

I’ll search and see if I can find anything on those error messages.
I followed all advice on here and continued to have the same problem. I decided to upgrade the installation from within Fantastico. That got the site working again briefly. I’ll mark this thread resolved and start a new one whose subject more accurately reflects the problem that developed next.
I have been having similar problems with my site:
http://www.pioneerecology.com
I often can only see the following message:
Fatal error: Maximum execution time of 30 seconds exceeded inD:\Hosting\7454082\html\wp-includes\class-http.php on line 38
This stops me from seeing any of the webpages or accessing the admin page. Other days it works fine and I can’t see any real pattern or solution.
Is there a solution?
After getting the site working briefly, I lost it completely. I started to receive a white screen of death and took advice on another thread to upload a fresh download of WordPress. I then got this error message:
Warning: require_once(/home/complete/public_html/wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /home/complete/public_html/wp-blog-header.php on line 12
Fatal error: require_once() [function.require]: Failed opening required ‘/home/complete/public_html/wp-load.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/complete/public_html/wp-blog-header.php on line 12
I downloaded a copy of all files from my old installation before I uploaded the fresh download, so I could re-upload any individual files that had been present. The question is, which ones would get me back to a fully functioning installation?
Try re-uploading all files & folders – except the wp-content folder – from a fresh download of your version of WordPress.
I re-uploaded the files and folders except the wp-content folder. I now get a list of the files in my root directory when I navigate to the home page of the blog and the error messages I listed above when I navigate to any other page.
I’m also finding that when I navigate to the site, a number of files (including the wp-load.php file mentioned in the error message) spontaneously disappear. I have re-uploaded the missing files numerous times only to find them disappear again as soon as I load the page in any of my browsers.
I am working with my hosting provider’s support on this disappearing file problem. I thought I should mention it here, too, in case this is a problem that might be related to something in WordPress that I installed wrong.
I much appreciate the help.
I doubt that’s a WordPress issue.
My hosting provider identified the problem as being that I uploaded the files unzipped, directory by directory. He advised me to upload the zipped file to my server and then unzip it there.
That has given me a complete set of files of Version 3.1.2 on my server. The problem now is that that whole set of files is now one level down from where they are supposed to be.
In unzipping the files, an additional directory named /wordpress/ was created in my public_html directory. Do I need to move all the files and directories up one level manually via cpanel? Or is there some way I can accomplish this more efficiently, without the risk of messing up content that is supposed to appear on the site? Thanks again for the help.
Where did you originally install WordPress on your domain.
I originally installed it in public_html.
I have now moved all of the root files for the installation into public_html and renamed the old wp-admin, wp-content, and wp-includes as wp-admin-old, etc.
I then copied the wp-admin and other two directories from the fresh upload into public_html. I also copied all of my content-related files from wp-content-old into the appropriate places in the new wp-content directory.
The result is that I can now log in. I can also access all of the pages from the site through the dashboard. They show up perfectly well in the editing function.
When I navigate to the site through my browser (or click the View option for any of them through the dashboard), though, I get a pure white screen. Nothing on it. No source code, either.
What have I missed in getting this site working again?
