Thanks for reply.
I have shared ftp details there. and they have checked 2 hours , finally they said this is not plugin issue, this is sql server issue.
while my site is working fine , and able to upload product from admin panel and also users can upload product. But when they upload product getting below messages -
Your listing is not visible yet, it needs to be validated by admin
Your listing has been published
Both notification showing when uploading products. and when I publish product from Admin panel , that product goes for Item validation but not for user.
and one more thing - when I edit product and save the product, its showing for validation (means product deactivated) but not showing in Item Validation. and in Product list Activate option is disable.
