Must read PSA: Namecheap antivirus false positive is breaking Chevereto sites

Hello there,

If you are using Namecheap hosting you may be encountering the following error when trying to access your website:

Code:
An error occurred while loading Chevereto.

Which on inspection of error_log will show you:

Code:
[06-Sep-2026 04:45:16 UTC] [CHEVERETO LOAD ERROR] Error: Failed opening required '/home/<REDACTED>/public_html/app/vendor/composer/../../src/Legacy/G/functions.php' (include_path='.:/opt/alt/php82/usr/share/pear:/opt/alt/php82/usr/share/php:/usr/share/pear:/usr/share/php') /home/<REDACTED>/public_html/app/vendor/composer/autoload_real.php:42

And if you try to manually upload the missing file:

Code:
YARA.nc_php_webshell_1ff7243525f942b3f52756820277981d.UNOFFICIAL FOUND

This is a custom AV rule created by Namecheap which is false-positive flagging our app/src/Legacy/G/functions.php file as a web shell (virus), and it is rapidly breaking many websites hosted with this provider as they seem to be rolling out this progressively.

This was officially spotted on August 11, and it may be related to other incidents (link, link).

Here's the VirusTotal check on the alleged file, and Shellpub analysis on the whole G folder which confirms that the file doesn't contain any web shell nor virus.

The recommended action is to migrate your Chevereto installation to another provider as Namecheap hosting doesn't offer any way to disable or fine-tune this AV system, it works at system level affecting cPanel file manager and also CLI. I'm afraid there's no way to skip it.

You may also try to contact support and reference to this announcement so they can fix their systems and don't miss you as a customer.

Cheers,
Rodolfo.
