Can't login in Admin CP and Front End

[Vendeira]

Hello,

 

Some users have problem in login on Front End. I go to Admin CP and on Friendly URLs (i already have the three option enable) click on Save and lost the access to Admin CP. Now when I login give me this error:

 

"Unable to access this siteThe web page at https://****/?app=core&module=system&controller=login&ref= may be temporarily down or may have been permanently moved to a new web address.
ERR_FAILED"

 

Anyone can help me to recovery access?

 

Thank you
