Compatibility with GTranslate (Translation Proxy)

Hi again,

here some more information.
1.) The problem exists since I migrated to a new hosting provider. I did NOT deactivate NinjaFirewall before migration (didn’t know that, sorry for that). After mmigration I have deleted the nfwlog-folder, re-installed the plugin and it basically works (as I can see from the log, several requests are blocked or sanitized). I don’t assume there is a problem from that.
However, the hosting provider I am using has set:
auto_prepend_file = no value

2.) the results from wp-check.php:

If there’s nothing in the log, check the “Firewall Policies > Advanced Policies > HTTP response headers” section. Did you enable some of those policies? If you did, they may block the request. You can check this by using your browser’s console. See this post: https://blog.nintechnet.com/securing-wordpress-with-a-web-application-firewall-ninjafirewall/?#http-response-headers

Thanks for the reply. I have set everything in “advanced policies” to no / unchecked. As a result I get the follwowing Header-Info:

General:
Request URL: https://www.xxx.de/es/categor%C3%ADa/alojamiento/
Request Method: GET

Remote Address: 85.13.xxx.xxx:443

But I think this is just the response I get from the GTranslate proxy server. As far as I understand, this proxy server is between my browser and the original server, therefore I cannot see the original HTTP Response-Header coming from my website. I just get the HTTP Response from the proxy. Right?
Any other idea?

When I request the “/es/categoría/alojamiento/” page on your site, it throws a 404 error. Is that normal?

Hi,
thanks for your reply. I have to admitt that I deactivated NinjaFirewall in the meantime, using another security plugin. It was too difficult to analyze the error for me, talking to three different parties (Hosting Provider / GTranslate / NinjaFirewall). Somehow, in this constellation, it didn’t work.
Sorry for that. However, I will recommend this plugin!
