Ok, running out of ideas. Let me just run down what I think you’ve done so far, just in case we did miss something.
1. You manually reset your plugins. No change.
2. You accessed your server via FTP or SFTP, navigated to /wp-content/themes/
and renamed the directory of your currently active theme to force the Default theme (WordPress 1.5 – 2.9.2) or the Twenty Ten theme (WordPress 3.0 and higher) to activate. No change.
3. You downloaded WordPress again and deleted then replaced your copies of everything except the wp-config.php
file and the /wp-content/
directory with fresh copies from the download. No change.
4. You repaired the database. No change.
5. You attempted increase memory by all four methods listed above, including contacting your hosting provider. No change.
6. You installed a fresh test blog which worked perfectly.
Is this an accurate list?
