Error updating to 3.2.0. Error in SQL Syntax Limit1

-- url of the page with the problem -- : staging1.restorationuk.com/

-- Joomla version -- : 3.7.5
-- PHP version -- : 5.6.31
-- Browser(s) name and version -- : Chrome

Hello,
My Hikashop version is currently on 2.6.4 and I am trying to update to 3.2.0 by installing the latest version via Joomla Install but I keep receiving a component error.

I also I receive an error saying:
"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 1' at line 1"

How can I resolve this?

Thanks

Thanks but non of that helps me. Turning on debug can't see any difference in the error message. In debug the Database Queries says it has found 6 duplicates. Not sure if this means anything.

Adding this :parent::__construct($message."\r\n".$query, $code, $previous);" to the executing.php file just creates a white blank page.

I am not sure what you mean by the patch but I have re downloaded the 3.2.0 version and it has installed fine.

Thanks for your help
