Publishing Shogun-built blog posts triggers: “Liquid error: Error in tag ‘section’ – ‘article-template’ is not a valid section type” on the live page. Liquid is Shopify’s templating language; a section type refers to a theme section file.
Diagnosis: the theme’s article-template.liquid file is missing or misnamed. This prevents Shopify from rendering the blog article section.
Proposed fix: roll back the relevant .liquid file to a previous version via Online Store > Themes > Actions > Edit code > Sections > article-template.liquid > Older versions. Images in the thread illustrate using the “Older versions” dropdown to restore code.
Additional guidance: back up your theme before making changes. A linked tutorial offers approaches for similar Liquid errors.
Latest update: after resetting to the original version, the error persists. The user requested direct assistance.
Outcome and next steps: account-specific troubleshooting wasn’t provided in the forum. The user was directed to contact Shopify Support (log in via the provided link and create a support request). Status: unresolved in-thread; escalated to live support.

I’ve been trying to post a few blogs that built on shogun but every time I set them live it comes up with this message: “Liquid error: Error in tag ‘section’ - ‘article-template’ is not a valid section type” on the live page.
This error is due to the file article-template.liquid not being found in your theme. Not sure if you have done any modifications to your theme files but it looks like it may have been deleted or there is a misspelling on the file name.
Shopify knows that errors are just human nature, so we have provided a way to undo changes made to a code file in your theme over time. Rather than trying to re-implement your product code, my first suggestion is to try rolling back your .liquid files individually to a time and date before you made the changes.
From your Shopify admin, go to Online Store > Themes.
Find the theme you want to edit, and then click Actions > Edit code.
Click on one of the files under the relevant folder in which you want to undo changes (Sections > article-template.liquid).
Click the drop-down menu to select an older version. Clicking a date stamp will roll the code back to that saved version. If you remember when you made the changes, you can return to the state of the file before your changes.
If you remember when you made the changes, you can return to the state of the file before your changes. Finally, don’t forget to hit that green save button!
Here is another tutorial where a Shopify Expert has provided a solution to solve similar liquid errors.
Although the method applied here is effective in undoing your changes, the best way to protect yourself is to always back up your theme before making any changes.
