elgg redirect error

Olá pessoal tem uma rede social em um site, entrando na tela de login da rede social e inserindo dados e confirmando que o elgg retorna à página principal do site e não faz login na rede social.

Tentei verificar o .htaccess e está tudo correto, ele não encontra o arquivo de ação / login que eu acho.



htaccess social network mod rewwrite
<IfModule mod_rewrite.c>

RewriteEngine on

# If Elgg is in a subdirectory on your site, you might need to add a RewriteBase line
# containing the path from your site root to elgg's root. e.g. If your site is
# http://example.com/ and Elgg is in http://example.com/sites/elgg/, you might need
#RewriteBase /sites/elgg/
# here, only without the # in front.
# If you're not running Elgg in a subdirectory on your site, but still getting lots
# of 404 errors beyond the front page, you could instead try:
RewriteBase /

# If your users receive the message "Sorry, logging in from a different domain is not permitted"
# you must make sure your login form is served from the same hostname as your site pages.
# See http://learn.elgg.org/en/stable/appendix/faqs/general.html#login-token-mismatch for more info.
# If you must add RewriteRules to change hostname, add them directly below (above all the others)

# explicity allow access for the .well-known directory
RewriteRule "^.well-known/" - [L]

# hide all dot files/dirs (.git)
RewriteRule (^\.|/\.) - [F]

# Everything else that isn't a file gets routed through Elgg
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?__elgg_uri=$1 [QSA,L]
