I am in the process of building a shop on wordpress using woocommerce. All is well except that at checkout there is an endless spinning wheel blocking the payment processing.
I have checked the error logs - which show no errors
I have disabled all plug ins - which makes no difference
I have reverted to the default woocommerce shopfront theme - which has the same result.
The console shows no errors.
I have also followed the instructions here https://docs.woocommerce.com/document/endless-loadingspinner-on-the-checkout-page/ which assumes its a memory limit issue. This did not work.
So, after a bit of digging I found some reference here https://mikejolley.com/2015/11/12/debugging-unexpected-token-in-woocommerce-2-4/ and here https://www.maxsangster.com/blog/woocommerce-endless-loading-spinner-on-checkout/
Referring to these two pages I have been able to see that the json response from /?wc-ajax=checkout is just returning HTML which I would imagine is where the issue is.
However I am running an Apache server rather than Nginx as has been mentioned in some threads and articles. Assuming there is a server misconfiguration of the server or something that needs changing what might that be? Bearing in mind that I do not have direct access to this, so will need to be asking someone else to sort it out for me.
And finally if there is something else I can try what might that be?
Thank you to #plushyObject for generating the spark for this one.
The issue turned out that I had a legacy static html holding page in place as the site's homepage rather than having one set up with wordpress. Simply removing the .html page and letting wordpress's homepage take over solves the problem.
The moral of the story create your holding page in wordpress.
Go to Google Developer Tools, then Go to the Network tab. Click the button and make the request and let that bad boy spin out.
You mentioned the response is returning HTML. Click on the request that goes out that appears to be taking forever (/?wc-ajax=checkout) and then click on the Preview tab to display that HTML. I bet it shows an error or a clue, anyway.
In my case the checkout was working fine on Desktop but not on Mobile. After many search on internet I read the solution of #UntitledGraphic.
I had set a redirect in ht-access. The redirect was showing a different home page for mobile. When I removed it, the error gone. I checked back & forth and was sure the ht-access redirect was the problem.
If you have set any redirect in the Htaccess then remove it. This will solve your issue in this case.
I also checked the redirect code on function.php instead of htaccess again the problem appeared. So finally removed the redirection.
In my own case the redirection was the issue. So I had to delete the redirect I created via Cpanel.
I have just started developing for a few weeks now and I bought a domain, but when I upload the files on live, the website looks different than what I have uploaded. Now, this gets fixed when I clear my cache. The problem is that my visitors enter, they see the page in a way, and after I update it they see it as the previous version!
Is there any possible solution for this? I don't want my visitors to clear cache every time I make a change on my website!
This is quite probable to be due to css cache. Your server is loading a cached version. You can specify the cached time in a few ways. Etags and htaccess (on apache) are the most common.
A very simple trick is just to add at the end of your style link url (where you load your main style in the head of the document) a get-like parameter: just like this:
main.css?v=2
I had this problem where CloudFlare wouldn't cache any of my pages because all of my pages returned session cookies. I've fixed this with a own written method, which removes unnecessary cookies from my response header. It's based on the same idea used and described here https://github.com/HaiFangHui/sessionmonster.
Currenlty i'm having this situation which is driving me bananas and i was hoping someone could help me out a little bit with your expertise about this subject.
I'm having this problem that after i login within my site after CloudFlare had it's chance to cache the page in a previous request... It will do that permanently untill the Edge TTL time expires.
Since the official CloudFlare documentation states it will not cache a page if it contains cookies i was hoping that after a succesfull login attempt it will serve a live/personalized version of the page. But so it seems that is not the case.
Does somebody know if this is normal? Of course i'm interested in knowing a way to circumvent this. I'm wondering how other sites solves this problem. My assumption would be i wouldn't be the first one having this issue.
Any advice regarding this subject would be greatly appreciated.
So it seems like supplying a "Bypass cache" setting is the solution.
It's only available on a paid plan.

I have an application running in Azure (trial account). So far so good, everything has been nice, except for a long deploy times (10-15 minutes).
I've done a deploy recently and got a lot of weird bugs I cannot trace. For example, if I log in and thus a cookie is created (I use FormsAuthentication) all I get from the application is a blank page, as in, absolutely nothing is sent to the browser. The application works fine in the ASP.NET Web Dev Server, IIS Express, even the Azure Emulator!
What could be the issue? Searching the web hasn't been much help, with only a couple of unrelated issues.
I tried logging into the site (if I correctly understood from one if the comments, the url is versulo.com) and I didn't get any blank page with 404 status code.
However, there is another problem I spotted. Your site seems to be implementing caching inappropriately. The main page, the one from which you trigger the login and which is dynamic in nature contains an Expires header set at 5 minutes after the pages first load. That means that each call or redirect to that page within 5 minutes since it was first loaded, will be served from the browser's cache.
Because of that, after I login into your application I am redirected back to the home page which looks like I am not logged in. If I force a F5 refresh on the browser, then the page will indeed show me as logged in.
If instead of a refresh I try to login again (which is what I did in my first trials, since it looked like the login didn't work in the first time), I am getting an error page with the following message:
Sorry, there has been an error on the server.
500
The page looks like an application error page and even if it displays the 500 number, it is actually served with an HTTP 200.
So, while I am not 100% sure if this is also the cause of the problem described by you, you should remove the Expires headers from the dynamic pages your application is serving.
This can be because you're combining Forms Authentication with multiple instances. Are you using multiple instances? If that's the case, could you:
Try to change it to 1 instance. Does this fix the issue?
Try to make the following change to the web.config (configure machineKey): http://msdn.microsoft.com/en-us/library/ff649308.aspx
some partial views are not rendered at all;
Do you mean some pages are working fine, but others are not? It would be better if you can point out a pattern on what’s working and what’s not? For now, please make sure all referenced assemblies (except for default .NET assemblies and Windows Azure runtime) have Copy Local set to true. For example, MVC assemblies are considered as extensions to .NET, so please set Copy Local to true. In addition, you can also try to use Fiddler to monitor the requests to see what’s returned from the server.

Could you provide a link to the application, or perhaps some source code?
When you say 'blank page', what is actually returned, a 404 / 500?
Have you inspected the IIS logs, or added some trace information to your code?
Have you tried accessing the service using it's ip address rather than domain name?
