Can't get into Dashboard after automatic 4.2.3 upgrade

Try downloading WordPress again and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

Thanks James. I uploaded 4.2.2 again because that was working before the upgrade and now I can get into my dashboard but no where else. WordPress also automatically upgraded me again to 4.2.3. Also now my site on the net comes up with a white screen on 3 different browsers. I’ll try it your way now and see what happens.

If it still doesn’t work, try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, 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 to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

Thanks Jeff, I reinstalled everything with a password change on my database and everything is working now. There was a problem with the theme not being compatible with the new update.
I appreciated the help.

You’re welcome!
