Falling into a Blackhole!

Hi gastronimo,

First of all, I must apologize not to provide the document about blackhole.webpagetest.org on W.org.

It’s supposedly a Web Page Optimization/Performance tool

You’re right!. The blackhole.webpagetest.org is used to analyze frontend Single Points Of Failure (SPOF) of the page.

I guess you’ve selected 30X for a response code which would redirect you to the blackhole. Please refer to this document: https://www.ipgeoblock.com/codex/customizing-the-response.html

(I should change this 30X functionality in the future, right?)

But the true reason you’re unexpectedly redirected to it is that a javascript error happens somewhere in your admin pages. Because “Zero-day Exploit Prevention” needs javascript to be excuted properly.

So please

1. Select 403 Forbidden for a respond code.
2. Disable Zero-day Exploit Prevention at least for “Admin area”.
3. Confirm if there is a javascript error on the page you had experience of this issue, and find the error message on your browser.

I can tell you how to confirm js errors if you let me know about the browser you’re using.

The possible reason why this issue happens is that IPGB may conflict with other plugins or themes. So I appreciate if you tell me about all the activated plugins and about your theme.

Thank you for your opening this issue!

Tok,

I appreciate the rapid and clear response!

I reset to 403 and removed Admin page ZDE, for now. The loadtime is excellent again- no blackhole.

As for JS errors, at least on the WP-Admin/Dashboard and also Settings/ IP Geo Block config page, the only thing that shows in my FF47 Console is:
‘mozHidden’ and ‘mozVisibilityState’ are deprecated. Please use the unprefixed ‘hidden’ and ‘visibilityState’ instead. browser_overlay.js:652:0

Oh, and this just popped up, but seems inconsequential to the issue at hand:
This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning; see https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects for further details and to join the discussion on related tools and features! options-general.ph

Anyhoo, now I know what to stay away from and will revise the IPGB CODEX again.

Blessings!

Hi gastronimo,

Thank you for your time to investigate the cause of this issue. I also use FF47 with Firebug!

Even when you disable ZDE, “wp-content/plugins/ip-geo-block/admin/js/authenticate.min.js” adds nonce onto your every request to the admin pages or ajax like “https://localhost/wp-admin/options-general.php?page=ip-geo-block&tab=0&ip-geo-block-auth-nonce=e39be45dac“. So if you can’t find “ip-geo-block-auth-nonce=...” in your requests, then something bad happnes.

I hope this may help you a little bit to understand the behavior of this plugin.

I appreciate you if you find something related to this issue. I never hesitate to offer my effort to you to solve this issue. Please tell me whatever you expect me at any time.

Thanks!

Yessir,

the ‘nonce’ is still added to my URLs.

As I get closer to production, I may investigate the issue further, but for now- issue RESOLVED.

Stay great!
