I want to enable the ngxblocker for my site. Here is my setup:

ubuntu 20.04

# wo site create example.com --wp --php74 -le --hsts --wpfc
# wo stack install --ngxblocker
# wo site update example.com --ngxblocker

after running the last command, I get the below error:

Testing Nginx configuration     [OK]
Reloading Nginx                 [OK]
Testing Nginx configuration     [OK]
