This is a mystery. We have a complex password for the Admin login. This has been a test site for us to see how NOP performs, and as such, we have added a few well known plugins. Perhaps one of those is a backdoor?
Hi jariwalakrunal, Thanks for your help. As well as ssolescu I saw the same in different devices (windows, android, Chrome, IE )with different ISP connections (see related post in previous box)
Seems like its working fine at this point of time from my end. Check here (http://imageupper.com/s02/1/4/H14202945391628985_1.png). I have checked this website http://www.unidenparts.com - and from a look it seems to be Magento not nopCommerce!
Just found your another post here. It will be great if you can share link to your site.
