Ok, I have started having this problem. I am running Nop 2.3 with Arxive as my host. It has been running fine for about a year now. Just few days ago I have started having problems in the administration mode. When I try to look at the customers I am getting the following error. I can down load the database to my local machine and it works just fine. I am in the process of upgrading to Nop 2.8. When I upgrade the database and try to run it on Nop 2.8 installed on another domain on Arvixe I am getting the same error, but again it works fine when I have downloaded it and run it on my local machine. Any thought would be appreciated.
