404 Page Errors Disappear on Reload

I have purged all the cache from the plugin and from the CDN as well. However, this does not resolve the issue.

Update:

I did some more research. It looks like the page keeps showing the 404 error if I reload it using the “reload” icon. I also get the error on using CTRL + F5 for fore refresh. However, if I go to the address bar and press enter it loads the actual webpage.

Hi,

Did you enable instant click ?

may I have the report number ?

you can it in toolbox -> report -> click “send to LiteSpeed”

Best regards,

Hi @qtwrk,

Here is my report number: CVQYBSXX.

I don’t think I have instant click enabled. Where is this setting? I will just check to be sure.

Here is my understanding of the situation so far. I hope it helps:

1. The page actually exists on the website. I can visit it by directly typing the URL in the address bar.

2. The page is supposed to handle some $_POST data from a form submitted on another page. However, it seems to give a 404 error whenever there is any actual $_POST data.

Thanks.

Hi,

Could you please bypass QC for the time being and try again ?

I feel might be bug on QC-side

Best regards,

I flushed the CDN cache, bypassed the CDN, purged the cache from LiteSpeed plugin but the error still persists.

It started happening yesterday. The page was working properly before that. ??

I added ?LSCWP_CTRL=before_optm in the URL of both the pages. One where I fill the data and the second where I process the data. I still got the same 404 error on submission.

Thanks.

When the page gives a 404, the response headers contain the following:

link: <https://mydomain.com/wp-json/>; rel="https://api.w.org/"

When the page loads properly, the response headers contain the following:

link: <https://mydomain.com/wp-json/>; rel="https://api.w.org/"
link: <https://mydomain.com/wp-json/wp/v2/pages/15431>; rel="alternate"; type="application/json"
link: <https://mydomain.com/?p=15431>; rel=shortlink

in this particular order. Does that help in figuring out the issue?

All other response headers are exactly the same.

Thanks.

Hi,

It works when LSCWP is OFF, right ?

Could you please check the server access log , see if they hit same URL ?

does this request rely on POST data or something to get some parameters or something ?

Best regards,

Hi @qtwrk ??

For some reason, the error only occurs when the name attribute of a form element is set to name="name". If I use a different name attribute value like name="first-name" or if I remove this element, the error disappears.

I have changed the value of the attribute. Maybe this error was unrelated to LiteSpeed.

Thanks.

Hi,

hmmmm , not sure , maybe that name is conflicted or already-used somewhere ?

Hi,

I’m going to mark this topic “Resolved”, due to lack of activity.

If you still need help, please feel free to re-open it.
