Hello Martin T.

Apology for the inconvenience. I have checked the template with all things updated. But I have not found the issue. Please clear your Joomla cache and Browser's cache and then check. If possible, then check with a different browser.

If the issue still remains, then share your administrator access here to check the issue. Use the Hidden Content box to share the credentials. Make sure that you have a full site backup before sharing.

Best regards

I’m uploading two images again where you can see the issue. You can also find the error on your demo site. If you open the demo site, you need to, for example, open the first article, Slow Grilled Chinese Char.... You’ll notice that the modules are loaded on the left. However, these modules should not be loaded when an article is opened.

Here is the first image. This view is still OK: https://www.kgv-exerzierplatz.de/picture-01.jpg

Here is the second image: https://www.kgv-exerzierplatz.de/picture-02.jpg

When you open an article, you can see the modules still being displayed on the left side. Articles need to be displayed in full-screen mode again, and the modules must disappear when an article is opened.

This issue only started occurring after the Helix update.

Please use this CSS to Template Options -> Custom Code -> Custom CSS

.view-article #sp-left {
    display: none;
}
.view-article #sp-component{
    width: 100%;
}

Then the left module will not be shown on the article details page and article will take the full width.
