WordPress blank screen error solution

Stumbled upon an error: WordPress admin pages just went blank. No error reports, nothing. Discovered two possible reasons for it:

  • corrupted WordPress files.
  • White space after last entry in wp-config.php file.

Solutions:

If files are corrupted (incomplete uploads, for example): just use good ftp client, upload again. If curious: I use FireFTP for Firefox addon.

Take notice that files can be corrupted by malicious code too. In that case, change your passwords before uploading new versions of files.

If it doesn't help: check your wp-config.php file. Notepad++ is good for that. If you see white-space and / or endline characters at the end of your file, delete them.
