you testing permanent redirects. never this, causes weird unreproducable bugs, after changing rule wrong.

you have rule makes no sense whatsoever:

rewritecond %{request_uri} ^(.*)/(.*)$  rewriterule . %1/%2 [r=301,l] 

this infinite loop redirects on , on same page. unclear me want accomplish rule, delete it. delete cache in browser, close browser , reopen it. should clear cached redirect.
