After a website redesign
New addresses, old links everywhere. LayerAssist lists which old pages return 404 and redirects each one to its new home.
Pages that answer with an error, found and fixed.
A page can be online and still broken: “404 Not Found”, “500 Internal Server Error”, “Too many redirects”. LayerAssist reads the status codes your pages return, explains them and fixes the cause.
At a glance
- In chatIn chat, it opens the pages you name like a visitor, reads each status code and redirect, and traces every error to its cause.
- AutomationAs your own automation, it can check a list of important pages on a schedule and tell you when one stops answering “200 OK”.
- Built-in monitorThe built-in availability monitor alerts you when your site doesn’t answer at all.
- Not available yetA built-in monitor that alerts on error codes, such as a page answering 500, isn’t available yet.
A site can be “up” and still turn visitors away
Uptime checkers say a site is up as long as the server answers. But when the answer is “404 Not Found” on your best product, “500 Internal Server Error” at the checkout or a redirect loop on the homepage, visitors leave just the same.
Search engines notice too: pages that return errors drop out of the results, and redirects that go in circles waste the visits that do arrive. The status code is the first clue to what’s wrong — if someone reads it.
Common errors and what they mean
- 404 Not Found: the address leads nowhere, usually a moved or deleted page
- 403 Forbidden: the server refuses, usually permissions or a security rule
- 500 Internal Server Error: the site’s code or settings crashed
- 502, 503 or 504: what runs behind the site is down, overloaded or too slow
Why pages start returning errors
A site move or new page addresses
After a migration or a change to the link structure, old links and search results point to addresses that no longer exist.
A broken .htaccess or server rule
One wrong line in a rewrite or redirect rule can cause 500 errors or endless redirects across the whole site.
File permissions and security rules
Files the web server can’t read, or a firewall rule that’s too strict, turn into 403 errors.
PHP or the application crashing
A plugin error, a missing extension or a memory limit makes pages fail with 500, while a stopped PHP service shows 502 or 503.
How LayerAssist deals with error pages
It starts where a visitor starts — the address — and follows the trail to the server.
Reads the real answer
It requests the page and records the status code, every redirect on the way and how long the answer took.
Follows redirects to the end
It shows each hop of a redirect chain, so a loop between http, https, www and a CDN is easy to see.
Matches the code to its cause
With access to your hosting or server, it reads the error log, the rewrite rules and the permissions behind each error.
Fixes, then checks again
It corrects the rule, permission or setting, adds redirects for moved pages and requests the page again to confirm it answers “200 OK”.
Example: a contact page that returns 403
What it checks
- /contact: 403 Forbidden for visitors from several countries
- /contact: 200 OK when signed in
- Security plugin: a country block meant for the login page applies to every page
- File permissions: correct
What it changes
Limited the country block to the admin login page
What you get
- Errors found on the pages that matter, not just the homepage
- Every code explained in plain words
- Redirect loops and broken links fixed at their source
- A second check after every fix
Real situations
A shop with 502 errors at busy times
The checkout fails only when traffic is high. LayerAssist links the 502 to a PHP service that runs out of workers and raises the limit.
A blog after a hosting change
Every post returns 404 except the homepage: the rewrite rules didn’t come along with the move. LayerAssist restores them.
How to check and fix HTTP errors with LayerAssist
Name the pages that matter
In chat, list the pages to check, or simply describe what visitors see.
Connect your hosting or server
To fix the cause, LayerAssist needs access to where the site lives: a hosting panel, FTP or SSH.
Let it test and fix
It reads the status codes, finds the cause, makes the fix and checks each page again.
Keep an eye on them
Ask for a regular check of your key pages as an automation, and add the availability monitor for outages.
Questions about HTTP status codes
It’s the three-digit answer a server gives for every page: 200 means OK, 301 and 302 are redirects, 404 means not found, and codes in the 500s mean something failed on the server.
No. It alerts you when your site stops answering. A page that answers with an error code needs its own check: ask in chat, or set one up as your own automation.
Yes. It follows the chain hop by hop, finds which rule — on the server, in the site’s settings or at a CDN — sends visitors in circles, and corrects it.
Yes. It matches old addresses to new ones, adds permanent (301) redirects and checks that each old link lands on the right page.
