Language school · October 2026 · reconstruction and migration
Corporate offer without hidden ads.
The website looked like a regular school website. Its code contained casino advertisements, and on the offer's pages there were links to job writing websites. The new version was created using a separate code, with school content and without the old WordPress.
- 25 pages
- built in the new version
- Without WordPress
- without its theme, plugins and base
- Copy of the old website
- preserved outside the public catalog
01 / Problem
This was not visible on normal viewing.
The block about casinos has been moved almost a million pixels beyond the left edge of the screen. It was still in the page code, although the visitor couldn't see it.
The pages of the offer also include advertisements for three essay writing websites. Therefore, the website published content that was unrelated to the school's offer.
I confirmed the problem in the public code of the pages. Below you can see a recreated method of hiding the ad.

Casinos with a deposit of PLN 1
Minimum deposit casinos are a great option for regular players… casino deposit from PLN 1 are the best solution…

New school content page.
The reconstruction included 25 pages and a new layout. I moved the content and photos to the new version, without copying the old WordPress code.
After publication, I checked the addresses, redirections and files. The old installation was kept outside the public directory with the ability to undeploy.
What did the owner get?
- a new website presenting the school's offer
- published version without any unwanted ads found
- website without updating the theme and plugins WordPress
- a saved copy of the previous installation
This was a larger renovation with a separate estimate. The basic package includes up to 5 simple pages.
How I checked the problem and what the verification included
The October 19, 2026 review included public code and content from 64 published pages and entries retrieved via the WordPress API. I confirmed the most important findings directly in the pages' code. The recorded evidence included addresses, code snippets, and how the content was hidden.
It was not possible to clearly determine where the unwanted content was added. A detected outdated plugin is not enough to pinpoint the cause. I didn't make any break-in attempts. The migration involved a published website, and a full security assessment of the entire hosting account requires a separate scope.
The school name and advertising addresses have been omitted. The preview is a reconstruction from the saved copy, not a snapshot of the original page.
