Initial version: 188.8.131.52
Seems some hack issue suddenly my frontend customers were not able to login with correct password. I did change password from admin for user and tried to login, even that did not worked.
I also changed password in db put md5 value and tried it did not worked too.
Then I updated magento to 184.108.40.206, but still found same issue. I tried reindex, cleared cache.
Can you please tell steps to fix this?
