Hello, I have been having ongoing issues with Hikashop and would like to re-install the extension to see if it resolves my issues. Can you please tell me if by re-installing the extension I will lose my data and images. The issues I have faced have been things like the wrong number of products displaying in the category link on the Category view page. The links in the categories menu do not link to where they should, the characteristics are sometimes generating duplicate id numbers and the products view starts with incorrect rendering and then corrects itself. I would love to re-install and keep all of my images and product information. Is this possible? I would really appreciate your help.
Thanks

Hello,
Note that by re-installing Hikashop, you won't loose any information. It will just update the files and add new columns in the database if required.
Your views overrides, css overrides, language, configuration, orders, products will stay intact.

But be careful if you have modified directly an HikaShop file and you didn't use the backend interface for that. Because you could loose your modifications.

Making a backup is always a good security .

Mohamed, Thanks very much. I will backup first as I have customised some of the files to include payment by invoice etc. Sorry for the delayed response.
