ERR_HTTP2_PROTOCOL_ERROR

I wouldn’t know how to start reproducing this based on your description. Please provide the HTTP request and response data in full.

I go into the wordpress admin, on the side bar, click on Loco Translate, then clicked on plugin, then clicked on woocommerce, then clicked on new language. On this page, I selected WordPress Language – Chinese (taiwan), then Choose a location and I selected “Author: plugins/woocommerce/i18n/languages/woocommerce-zh_TW.po”, then I clicked “Start translating”, then it gave this HTTP2 error message.

I had the same problem due to gzip compression.

I added :
SetEnvIfNoCase Request_URI ^/wp-admin/admin-ajax\.php no-gzip dont-vary
in .htaccess file to fix this problem.

@guiguiweb Thanks for adding this.

Loco Translate manually sets the Content-Length of the JSON response, so any server module that compresses the content would have to modify that header. (Nginx removes it. I can’t comment on Apache).

There’s nothing to say that corporatei has the same issue, which is why I asked to see the HTTP data. Regardless, it sounds like a server issue unless it can be attributed to a bug in the plugin.

@timwhitlock I checked with goDaddy web hosting, and they couldn’t find out what the problem was. At first, they say that it maybe a DNS problem, which is not. They say to check with you guys.

@guiguiweb so should I try to modify the .htaccess file to include that sentence? Just add it in copy and paste right?

At first, they say that it maybe a DNS problem

Based on that response I would insist they refer me to someone who knows what they’re talking about.

Regarding your checking with us guys. I did ask to see your HTTP exchange. If you require any further suggestions from me, please post that.

What is a HTTP exchange, and how do I provide that information to you?

Use your browser’s network inspector. See here for help with Chrome: https://developers.google.com/web/tools/chrome-devtools/network/reference#headers

I need the full response headers and response body.

This is the request. I need the response headers and response body.

When I go to Network, then When i click on the link under the name, there are the tabs “Headers, Preview, Response, Initiator”. I clicked on “response” and I see this:

It says ‘Failed to load response data”

See this screenshot here.

That’s annoying. Can you not even see the response headers in the Headers tab?

Please use respectful language when you communicate here. I am an beginners to intermediate web developer and you should not use this tone.

Did you see the screenshots? I clicked on the response header and it shows nothing.

Maybe is easier if you take a screenshot of an example and circle it so I know where to properly find what you need instead of using rude tones.

Tone? its annoying that the response isn’t shown! How is that disrespectful?

I looked at your screenshot. Hence my comment. You didn’t post a screenshot of the headers tab. Which is why I followed with that.

This is a server issue, which I’m not obliged to help you with at all. And here I am at 8:30am still looking at your problem and you’re accusing me of rudeness.

I have nothing more to add to this. You’ve been given a good suggestion by guiguiweb. I suggest you try it. If it fails, pursue the issue with your hosting support.

Sorry I misunderstood your words, I did not know you were referring specifically to the empty header’s tab.

I thought the screenshot did show the header’s tab? this was under the network, headers? Under the headers tab, I don’t see anything related to “response”, I attach the screenshot here.

In this screenshot, under headers, I don’t see anything related to “response”, if that is what you were referring to.

Otherwise I will just try to modify the .htacesss as suggested by guiguiweb. I just thought it was a bug that’s why I reached out here.
