# Unfortunately something went wrong on the product page

## Description

The error "**Unfortunately, something went wrong.**" appears on the product page if you use our "ThemeWare® Customizing Plugin".

## Cause

In this case, the cause is an outdated version of the extension or an outdated customisation.

## Solution

1. Please remove the content in the following files:
   1. File "**main.scss**":
      * Delete everything
      * File location: `custom/plugins/TcinnCustomizing/src/Resources/app/storefront/src/scss/`
   2. File "**headline.html.twig**":
      * Delete everything from line 2
      * File location: `custom/plugins/TcinnCustomizing/src/Resources/views/storefront/page/product-detail/`
2. Then refresh the storefront once to transfer the changes to the storefront: [refreshing-the-storefront](https://knowledge.themeware.design/knowledge-base/tutorials/miscellaneous/refreshing-the-storefront "mention")
