Demo content is displayed as plain text and code instead of styled website

Hello,

I have purchased and installed the WoodMart theme. The activation was successful, and I imported demo content (Furniture and Furniture 2). However, after the import, my website is displayed incorrectly.

Instead of showing the styled demo pages, the site only displays plain text with HTML/CSS code output (like raw code on a white background). The header is visible, but the rest of the page is broken.

What I already checked:

WoodMart Core is active

Elementor is active

WooCommerce is active

No caching plugins are enabled

I cleared the browser cache and tried Ctrl+Shift+R

But the issue still persists.

Could you please advise how to fix this problem?

Thank you!
