Still blank pages after 3.3 upgrade

Try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins, using ftp rename plugins folder to plugins_hold and create a blank plugins folder If that resolves the issue, delete blank plugins folder and rename original back to plugins reactivate each one individually until you find the cause.

If that does not resolve the issue, try switching default theme twenty eleven theme (WordPress 3.0 and higher) to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the Default theme Twenty Ten theme (WordPress 3.0 and higher) to activate and hopefully rule-out a theme-specific issue.

If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via FTP or SFTP and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your FTP or SFTP client to view invisible files.

If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’ll need a more detailed error message.

Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.

Thank you for the tips!
I think I’m going to pass this on to my hosting provider. I’ve done almost all you’ve mentioned above except for the server error log. Unfortunately, I dont get any error message, just a blank page.

I think it’s either I’m not doing it right or there’s really an unseen problem here. Thanks anyway.

ok. i’ve got no clue…

done all the usual fixes… renamed/removed/reinstalled plugins & themes
checked the .htaccess and fiddled with all the various suggestions i found in the forums, basically, everything except a complete reinstall…

is that really my only option??

i manage 30 other wordpress sites and never had this problem … usually the fixes above will solve the problem.

is there any chance it could have something to do with the THEME??? (even tho i removed the theme files & that didn’t help.)

i’m grasping here – can’t finish invoicing this client if they can’t access the darn admin!!!

any further suggestions welcome..

The last option is to see error you get by following this steps

First check wp-config.php if you have any blank space before

<?php
as this needs to be on line one.

if there is none then try and add this code in next line

error_reporting(E_ALL); ini_set(‘display_errors’, 1);

In addition, add the following code above
/* That’s all, stop editing! Happy blogging. */ :

define( ‘WP_DEBUG’, true);

See what error you get.

If you already have line change false to true

and replace the files that are giving error from fresh WordPress download.

ok – this is curious…

thanks for those tips. here’s the result:

now – i use ultimate-google-analytics, si-contact-form, and wp-google-fonts in combination on MANY sites, and haven’t had this problem before.

i removed the plugins, removed the header functions from my child theme functions.php… neither of those things made a difference – still get the blank wp-admin…

so… new install it is, i guess ??
thanks for the help.

You could replace all files and folders except wp-content folder and wp-config.php may some file got corrupted.
