Background of the issue:
I am trying to login to my WordPress site using the URL lien caché.
(I'm only able to login changing the name of the WP plugin folder).
Symptoms:
I encountered a 500 Error with the log error: "too many redirects" from the server, even though all plugins were disabled except WPML.
Questions:
Why am I experiencing too many redirects when trying to login?
How can I resolve the 500 Error related to redirects?
