Hi @tylertork
This error would not be due to CORS (as you mentioned it does not send any data to a anyone else). A 414 error indicates “URL too long”. I checked on your website and I can reproduce the 414 error. The server seems to have a problem with a URL that has 370 characters which is fairly short for a URL. Any chance you could reach out to Siteground and ask them if they can increase this limit for you?
There might be also an additional workaround:
* Go to WP Admin dashboard
* Go to Matomo Analytics -> Settings
* In the tracking settings tab enabled the setting “Force POST requests”.
* Save and try again
This might solve the issue. Note that if you use any caching plugin like WP Rocket then you might have to clear the cache to see this change.
Could you give this a try? Hope it helps @tylertork and happy holidays.
With that hint, I was able to determine that iThemes Security plugin was blocking the request because it considers the URL too long. I deactivated that feature and now everything appears to be working.
Thanks.

Great, glad this works now @tylertork Any chance you could let me know where exactly I find this feature in that plugin? I’d have a look if we can workaround it in the future or to detect when it’s enabled and show a notice or so. Thanks for bringing this issue up and happy holidays.
Under Security, System Tweaks, look for “Filter Long URL Strings” checkbox.
I suppose you could try to get iThemes to change the limit and/or recognize and allow your specific type of request. You could also shorten your URL by using a relative URL for the “url” argument — though I realize that’s not a complete solution since the relative part could easily be quite long also.

Thanks for this @tylertork
In the next release we will detect this automatically and instruct to disable this setting. Thanks again, very appreciated @tylertork
