I have a Wordpress network where I run +/- 10 sites. Recently, I got a redirect error when accessing the wp-admin page for one of the sites. All sites in the network are working fine, I can also access their admin without any issue except for one site.
I get the error: ERR_TOO_MANY_REDIRECTS
Here is what I have done:
- clean all my cookies
- clean cache in browser, server and cloud
- rename htaccess
- rename plugin folder
- rename theme folder
- add define('COOKIE_DOMAIN', false); to wp-config
This site has exactly the same configuration as the others, I don't understand why I can't reach my admin page.
Do you have any idea?
