Overview
Completing a new WordPress installation should instantly give you access to your site's administrative control panel (/wp-admin). However, if you attempt to log in immediately following setup and your credentials are rejected, the page constantly refreshes, or you encounter a persistent login error screen, backend intervention is required.
When you cannot log in to WordPress after installation, it typically indicates a database user authentication sync failure, improper file permissions on administrative files, or an incomplete installer script execution within your hosting environment.
Common Causes of Post-Installation Login Errors
While an installer may report a successful setup, underlying server or database mismatches can block administrative access right away:
| Symptom | Primary Cause | Resolution Required |
| Invalid Credentials Error | Database user salt/hash generation failed during automated setup. | Live Agent must reset administrator password directly in the database. |
Redirect Loop on /wp-admin | Mismatched site URL / home URL values in the wp_options table. | Live Agent must verify domain path configuration in Plesk. |
| 403 Forbidden on Login | Incorrect file permissions on wp-login.php or wp-config.php. | Live Agent must reset file and folder ownership flags on the server. |
Can Users Self-Serve This Issue?
No, this issue cannot be resolved through self-service.
Because this failure occurs immediately upon setup, standard self-service recovery options—such as clicking "Lost your password?"—frequently fail because the underlying database or mail configuration is incomplete. Attempting repeated logins or reinstalling over an existing database can cause configuration locks or corrupt directory files.
If after installing WordPress you are unable to log in, please contact a live agent for assistance.
