Hi All

Fairly new to Opencart having recently seen the light.

We have an Opencart 2.0 installation on a dev server. The only add-on is the csv export/import system.

When viewing any category with products in it, I am getting the following message:

Warning: mysqli::query(): (21000/1242): Subquery returns more than 1 row in /home/vibewebs/public_html/dev/penfriend/system/library/db/mysqli.php on line 18Notice: Error: Subquery returns more than 1 row

Any help on this would be much appreciated. I have looked for duplicate product/manufacturer id's in phpmyadmin but nothing amiss found there

likely means your database tables are messed up


You could have 2 rows in product description for one product etc.

Also having the same problem, im also using the export import tool, ive been through the 20 products i just uploaded, no duplicates, spelling mistakes etc.. i'll keep looking though. Previously uploaded several times without fail so its something i entering into the spreadsheet thats causing the issue..

So i managed to sort the issue by choosing the option within the extension to delete old data before importing new..
Maybe that's what you need to do.

Visit and I would be happy to receive any thoughts or problems you pick up on! I am a new business, have had successfull previous companies and New to developing a software based website. Thank you.
