All latest VirtueMart Products will not displayed till user makes the login

[reneachter16]

Hello There... 

I started having a wired problem since yesterday with my VirtueMart site https://ihmafees.in/ All latest VirtueMart Products will not displayed till registered user makes the login first. But the old products are displayed fine as before

Site Joomla! version 3.5.0 Stable
VirtueMart Version 3.0.14

The latest products I added here https://ihmafees.in/index.php/hostel-fee-5k-monthly where page displayed as empty till registered user make the login.
Another related issue is, If old products get updated in any sort of way! They will disappear from related menu, till registered user makes the login.

Please suggest what can I do to rectify the problem... 

Regards & Thanks
Rene

Likely to be a permissions issue (check the ACL) but those versions are 5 years old and certainly insecure. There were problems with hackers a couple of years ago where they exploited a vulnerability in Joomla that enabled them to change permissions on sites and give themselves super admin rights & install malware. They were then able to remove evidence of their intrusion, but the malware remained.  I'm not saying that is the issue in your case, but I'd not rule it out as a possibility.
