Question

When accessing the following in Magento backend:

Magento Admin Panel > Newsletter > Newsletter Subscribers

I get the following error:

I did not change any code. I moved Magento lately and I think it happened after that.

Answer 1

I've seen this issue before where the BL_CustomGrid module loads 2 of the same tables and give you this issue. so your custom grid configuration is off. Try to remove it. or try to disable that module to see if indeed its the issue.
