Question: Domain in Plesk shows error 403: rewritten query string contains control characters or spaces
Symptoms- A domain in Plesk contains the %20 symbol in the link, for example:
https://www.example.com/something/link%202.
- After the Apache update to 2.4.41-4ubuntu3.14, these links become inaccessible in a browser with:
Forbidden
You don't have permission to access this resource.
Apache Server at www.example.com Port 443- The following error can be found in the domain's logs:
AH10411: Rewritten query string contains control characters or spacesCausemod_rewrite is now blocking "unsafe" requests.
Resolution- Perform one of the following:
- Adjust the website code (change URLs) and make them avoid using symbols such %20.
- Switch the domain from PHP-FPM to FastCGI in Domains > example.com > PHP Settings.
As a workaround, downgrade Apache on the server:
# apt install apache2=2.4.41-4ubuntu3 apache2=2.4.41-4ubuntu3 apache2-data=2.4.41-4ubuntu3 apache2-utils=2.4.41-4ubuntu3 apache2-bin=2.4.41-4ubuntu3
and forbid further apache updates.
