Closing this issue now – feel free to update if you need further help.

Hello!

Sorry to hear about your problem! In the CDN settings there is a big ON/OFF switch where you can quickly turn the CDN rewriting off in the event of problems.

Do you have more information on what was broken with the slider exactly? Perhaps you can enable again and I can check your site to investigate further?

Sometimes sliders load images differently than how our CDN would be able to rewrite image links in rendered HTML. Also some sliders (like master slider) have their own caching built in so you might have needed to clear the cache if there are problems.

Perhaps you can start by pasting the debug info in our plugin settings in this thread so I can see if there are other plugin conflicts happening as well?

Wow!

Very sorry for your experience. This is a free service that costs thousands of dollars per month in bandwidth charges to maintain.

You ultimately were able to reach out via submitting a contact form but for free tier we position support as being primarily available through the official support forums and our official discourse community forum.

Think of how much time it takes to offer free support and then offering a toll-free support phone service on top of that would be so incredibly taxing it would make offering free services like this completely not worthwhile.

There are so so many reasons why problems occur just generally with wordpress plugins from hosting environments (PHP, web services, security firewalls, anti DDoS measures) to other conflicting plugins on your site that can cause problems like caching plugins and just random plugins that you wouldn’t think that would conflict with something like this but do.

Usually someone posts in the support forum (and you can verify this yourself), I try my best to respond very quickly and offer support. Usually a troubleshooting interaction back-and-forth happens and in most cases I can resolve the problem.

This legal compliance thing you are mentioning doesnt make a whole lot of sense. So we offer a free service and have to sit by the phone for a toll free number to offer free support? Where is the incentive then for an open source community to develop and contribute free services?

The paid tier of our plugin offers 24x7x365 support because we can justify offering this level of support if you actually pay for services.

Sorry again for your experience but this bad review will hurt the free service that other people enjoy for literally thousands of other users.

Hello,

Thanks for using our service!

The error message on the link you provided is from your own web hosting service :

What happened?

This website is using a security service to protect itself from online attacks.

Sometimes web hosting services have security set to very sensitive levels where they think when one of our CDN endpoints fetches a url, it is an automated attack. Our IP addresses are from data centres (instead of residential) and they may have determined that because of that it might be a denial of service attack.

This has happened to a few other people who have reported in the support forums here. I have no control over the web hosting services but sometmies if you ask them to turn down the threshold for these sensitive security settings, it will help.

Alternatively you could ask them to whitelist all the IP addresses used in our CDN servers. You can reach out to us via email to ask for an IP list to request them whitelist.

Thanks

Hello,

Looks like when loading https://zetadisseny.es/?amp=1 on a mobile device produces an infinite redirect-loop.

Can you go to the debug tab of the Shift8 CDN plugin settings and paste the full list of installed / active plugins? It is likely another plugin is conflicting with how the page loads for example.

Thanks

Hello!

I looked into this and there is something on your side that is causing a problem with how the PDF renders which I will explain as best as I can.

The local version of the link works :

https://www.schadeck.eu/wp-content/plugins/pdfjs-viewer-shortcode/pdfjs/web/viewer.php?file=/wp-content/Erste_Schritte_mit_Shotcut-1.pdf&dButton=true&pButton=true&oButton=false&sButton=true#zoom=0&pagemode=none

But the CDN version of the link does not :

https://dd9i74amxnjv.cdn.shift8web.com/wp-content/plugins/pdfjs-viewer-shortcode/pdfjs/web/viewer.php?file=/wp-content/Erste_Schritte_mit_Shotcut-1.pdf&dButton=true&pButton=true&oButton=false&sButton=true#zoom=0&pagemode=none

This is because this is not a direct link to a static file. The CDN is confused because it is trying to pass a PHP file that pulls a local PDF to render in a viewer. The shortcode generator that you are using “PDFJS Viewer Shortcode” is causing this problem.

We cannot cache this as a static file because PHP has to render the PDF on the server side (on your site) for it to render in the browser. It is this barrier that is causing the PDF to not render and redirect to our company homepage (this is how a 404 is supposed to work).

To get the PDF working you will have to just link to the PDF as a direct file or perhaps you could try linking the direct path in the shortcode settings to go through the CDN?

For example a direct link to the PDF through the CDN will work :

https://dd9i74amxnjv.cdn.shift8web.com/wp-content/Erste_Schritte_mit_Shotcut-1.pdf

In the shortcode options for the pdfjs viewer, can you add a full URL for the PDF for it to load? For example :

https://www.schadeck.eu/wp-content/plugins/pdfjs-viewer-shortcode/pdfjs/web/viewer.php?file=https://dd9i74amxnjv.cdn.shift8web.com/wp-content/Erste_Schritte_mit_Shotcut-1.pdf&dButton=true&pButton=true&oButton=false&sButton=true#zoom=0&pagemode=none

If this is not possible, you will have to find another way to load your PDF as it wont work with our CDN (and most other CDNs).

I hope this was helpful!

Going to go ahead and close this – if you have any future problems, feel free to open a new issue.

Thanks!
