Some page constantly loading

23 Jul 2019, 23:34

Recently, some pages of the site have been found to be constantly loading and just show a dark blank screen with a loading icon. Even if I clear the site page cache and the browser's cache, it still has not changed. I also tried to rebulid the Preload Site Object, but still the same result, so can you please help analyze the reason? thank you very much!

Here are a few urls with this problem:

You are getting "500 internal server error" when loading the document:

Checking the SOURCE of the document, you will see it loads html and suddenly stops in the middle somewhere:

That means there is something that happens at that point, which causes the error, and that would have to be something character related. So, checking your diagnostics, I found that mbstring extension was missing:

Your PHP needs to have mbstring extension, which is a standard PHP extensions. It is used for character encoded, and would certainly be more important for websites using non-standard (non-latin) text. I am guessing your server upgraded their PHP version at some point, but this PHP version installed on server is missing mbstring.
