Fixing "No Language Defined" Error in VestaCP

Check If Language Files Exist

VestaCP language files are stored in:

For related VestaCP topics in this cluster, see Missing Language Files (variant) and Not Recognizing Language.

/usr/local/vesta/web/lang/

Run the following command to check if the language files exist:

ls -lah /usr/local/vesta/web/lang/

If you see files like en.php, ru.php, etc., proceed to Step 2.

If the folder is empty, reinstall the language files (see Step 4).

Set the Default Language in VestaCP

If the language file exists but isn't loading, manually set the language.

Edit the Vesta Configuration File

nano /usr/local/vesta/conf/vesta.conf

Find the LANGUAGE setting:

LANGUAGE='en'

If it's missing, add:

LANGUAGE='en'

Replace 'en' with your preferred language (ru, es, fr, etc.).

Save and restart VestaCP:

systemctl restart vesta

Fix File Permissions

If the language files exist but still don't load, fix the permissions.

Run:

chown -R root:root /usr/local/vesta/web/lang/
chmod -R 755 /usr/local/vesta/web/lang/

Restart VestaCP after fixing permissions:

systemctl restart vesta

Reinstall Missing Language Files

If the language folder is empty or corrupted, reinstall it.

Download the Language Pack

cd /usr/local/vesta/web/
git clone https://github.com/serghey-rodin/vesta.git vesta-lang

Move the Language Files

cp -r vesta-lang/web/lang/ /usr/local/vesta/web/

Remove Unnecessary Files

rm -rf vesta-lang

Restart VestaCP

systemctl restart vesta

Now your language settings should be restored!

Summary of Fixes

Now VestaCP should display the correct language!
