Hi @janzeman,
Could you try it in another browser?
Could you post your javascript console logs?
Thanks

What is the WordPress address and Site address?
Did you log in with the Cloudflare account that owns clipa.vu? Do you have multiple Cloudflare accounts?
Thanks,
John
Hello,
Thank you both for fast reactions.
I tried other browsers – the same result. Lately I tried in Google Chrome and opened Dev Tools > Console. I found this:
/web/wp-content/plugins/cloudflare/config.js?ver=3.2.1 Failed to load resource: the server responded with a status of 406 (Not Acceptable)
@john: Yes, the site address could be the problem. My WP is in subfolder so the settings are:
http://clipa.vu/web
http://clipa.vu
I have only one CF account and I used that one. As said with the same account I was able to work with the 2 other CF related plugins.
What to do next???

Hi @janzeman,
Do you have any firewall/security plugins? There might be a settings not allowing “application/javascript” MIME type.
Here is description of what the problem is.
I’ve seen this issue before. People had other plugins which blocked the request from the plugin. Please try to figure out if a plugin causes this and let us know of your result.
Thanks
Hello, yes, I use Wordfence. However after I fully disabled it is still shows the same. My WP is IIS hosted. I managed to get bit more info but I still do not know what to do…
Also I do not understand why the other plugins (i.e. Analytics For Cloudflare) have no any similar issue.
Error Summary
HTTP Error 406.0 – Not Acceptable
The resource cannot be displayed because the file extension is not being accepted by your browser.

Most likely causes:
The request was rejected because it contained an Accept header for a MIME type that is not supported for the requested file extension.
Things you can try:
Verify the MIME settings for the file extension that was requested to make sure this MIME type is acceptable.
Links and More Information
This error occurs when the client requests a file with a certain file extension and then specifies the Accept header with a MIME type that is different from the configuration of this file extension on the server. An example is requesting a file with the .doc extension and specifying an Accept header with text/xml instead of application/msword. Usually the client specifies */* for the Accept header, which allows the request to serve any MIME type.

Interesting. I just tried (still with disabled Wordfence) in just another browser (Opera) and now the settings appeared. I was able to enter CF Api key and mail and now it all works. And it also works in my default Chrome browser and it all seems to be working even after re-enabling of Wordfence.
Do you think you would be able to explain this?
Thanks for assisting.

Hello, I also asked my hosting provider support. They did a great job and came to very similar result: 406.
They explained that on their servers IIS is not able to accept header through JavaScript. Their suggested solution is to remove “opts.headers={Accept:”application/javascript”};” that appears twice in \wp-content\plugins\cloudflare\compiled.js file.
Maybe that can help you to find a generic solution for any future version?
