Wordpress ERR_TOO_MANY_REDIRECTS solution

Fault phenomenon

When logging in to the WordPress backend, the browser displays “ERR_TOO_MANY_REDIRECTS” As a result, it is impossible to log in to the backend normally.

Solution ideas and steps

• Check Cloud Flare HTTPS configuration - - OK
• Check the HTTPS configuration in the WEB server - - OK
• Check whether the siteurl and home values in the WordPress database start with https
• Check the value of HTTPS = ‘on’ in WP-Config.php

Result verification

Check whether the siteurl and home values in the WordPress database start with https

Because this data has turned off https before, it is impossible to log in to the backend to modify the default URL. So you can only enter the database to modify

Check the value of HTTPS = ‘on’ in WP-Config.php

The reason is also because in order to turn off https, this value is changed to off. After changing it to on again, the browser clears the cookies and press F5 to access it normally.
