i see your SQL query is correct. Please be sure that you have tables in your database.
Regarding permissions you should to change it manually via shell
Just run command chmod -R 755 /home/readyrep/public_html/AbanteCart/ to change it recursively  or do the same via hosting provider CPanel->Filemanager

Thank you for quick help abolabo. 
I am unsure how to check if tables are in database please advise.

there was no folder under my public_html named abanteCart.  There is one named AbanteCart.  I changed the name to AbanteCart the restore has finished processing without errors this time but still no access to site or admin panel.

Please advise

after changing readyrep/public_html/AbanteCart to readyrep/public_html/AbanteCart and finishing restore.  I have restored name of changed file under public_html back to AbanteCart as there is no storefront on site and no access to admin panel.

I forgot to mention permissions of this folder was set at 755

Please advise.
