X3Photo Gallery Forums

I don't know, I can't possibly diagnose these things without a link.

It suddenly happened without your intervention? Maybe something changed on server.

It's a fresh new install on my laptop as testing. I am located in Shanghai, so I am not sure whether some scripts could not be load because of the firewall, neither I visit the https://demo.photo.gallery/panel/, it displays the blank page.

You mean you don't even see the login page?

The main problem is the backend panel page could not pop up in my area, while the website can browse perfectly.

Ok so I guess it can be confirmed that the problem is the CDN provider, perhaps only temporarily. They claim to cover China:
http://www.jsdelivr.com/features/cdn-in-asia-and-china

The frontend works fine? Also the popup when clicking an image? The frontend actually has a redundancy fallback, so that if the CDN fails, it will load local-hosted version of a script.

Leo wrote:If that is the reason, how many script files need be localized, will they effect the performance?

The only reason is that it is fast and practical, loading a large amount of JS/CSS resources from a CDN provider on fast networks, through the new http/2 protocol. It would not affect performance too much though, if you host the files on your own server ... Especially since it's mostly a single user from a close location to the server that is using the panel.

It would require some working editing the templates and downloading all scripts to have a local-hosted setting. I can look into a non-CDN panel setting for next release, but it will be a while since we are busy with a new website right now.

Must say I'm a bit surprised that the CDN is not accessible, considering what they say, and their network map. What browser do you use? If Chrome, could you go to view -> developer -> developer tools -> network tab, and reload the page? It should show clearly in red what resources are failing to load.

Hmm, that's interesting ... It is actually the GOOGLE CDN that fails for your location. I thought since it's Google, it would be reliable, but seems not. You can fix it for your local version ... Open panel/footer.php, line 80: Replace with the following: I will look into this for next release, maybe implement a fallback. We actually load the JQUERY script from Google CDN, because it is most widespread. We might change to jsdelivr, which seems to work from your location.

right ...

This is now fixed in X3 Release [0.19]. We have changed from Google CDN to JSDelivr, which seems to work nicely in China.
