Failed to initialize NumberFormat

Many thanks for getting in touch. We’re currently investigating this issue, which so far we’ve had similar reports from Safari browser users.

So we can investigate this more it would be great it you could share the following information:

1. Your Site Health information. You can use this form to share privately if preferred.
2. Does this occur when you login to your site and check your browser from a Chrome browser?
3. At what stage does this occur (ie. Consistently when you click on the primary Site Kit primary dashboard)?

Let me know if you have any questions on the above.

Hi James,

Thanks for the follow-up.

1. I’ve submitted the form for the Site Health information.
2. No, it works in both Chrome and Firefox on MacOS
3. It happens for virtually all options for Site Kit: Dashboard, Search Console, and Analytics. Not for Adsense (not enabled) or Settings.

Let me know if there’s any other information I can provide to assist with troubleshooting.

Thanks!

Thanks for providing the additional details. As this may be occurring as a result of another plugin using the Google Charts Library please inform me of the same occurs when following the steps below:

1. Login to your site from a Chrome browser incognito window
2. Install and activate the Health Check & Troubleshooting plugin.
3. Navigate to “Plugins > Health Check & Troubleshooting > Troubleshoot”.
4. From the same screen click on the “Available Plugins” tab at the top right and then click on the “Enable” option next to “Site Kit by Google”
5. Attempt to view the same dashboards once more

If the same doesn’t occur then in order to point a conflict you can enable your other active plugins once by one while remaining in troubleshooting mode.

You can exit troubleshooting mode afterwards.

Let me know if you have any questions on the above.

Thanks, James. I’ll give that a shot. But I’m wondering if it has anything to do with the bug in Safari 14.1 I just read about (https://appleinsider.com/articles/21/05/04/macos-bugs-causing-sporadic-browsing-issues-with-safari-firefox-others/)?

It’s mostly an issue with newer versions of MacOS, but apparently is still trouble for MacOS Mojave that I’m running.

Interesting! I’ll add this to the GitHub issue for the team to review, while I also set some time aside myself this week to test.

I’ll keep you updated with any insights I can find. In the meantime if you do have time yourself please follow the suggested steps previous mentioned – excluding the first step “Login to your site from a Chrome browser incognito window“. I seem to have missed your reference that it doesn’t occur with other browsers.

Hi again, James.

Just used the Health Check & Troublshooting plugin (awesome tool, good to know about), and with JUST the Google Site Kit plugin enabled, the problem still exists when viewing in Safari 14.1

So… I’m guessing this is actually a result of that MacOS/Safari 14.1 bug and isn’t an issue with the Site Kit plugin (or conflict with any other plugin or theme).

Hope Apple releases a fix soon! ??

Many thanks for the update, good to know. While I don’t have any additional troubleshooting steps to suggest in order to avoid this I will performing some additional testing and keep you updated with any findings. This issue may be as you referenced on the Safari side although we will investigate further.

@thervgeeks While we’re still investigating this issue can you share whether the same issuer persists when selecting another language active while still using Safari 14.1?

Hi James. Just changed my system language (System Preferences / Language & Region) from “US” to “United Kingdom”. Rebooted the computer and checked the Site Kit page in Safari. Same issue, no change.

Do you think it’s a problem with ALL English language selections? Or is there somewhere else I should be changing the language selection (didn’t see one in Safari/Preferences).

Many thanks for checking this. I don’t think it’s an issue with English languages although we were considering the possibility of some language based conflicts. We will however continue to investigate as much as we can on our side.

I’ll also keep you updated here with any additional findings.

Just to keep you informed we’re still investigating this issue. While doing so it would be great if you could share the following as we’ve been unsuccessful in consistently recreating this so far:

1. Do you have any additional Safari browser extensions installed?
2. Do you have any Safari experimental features enabled?

Let me know if you have any questions on the above.

Hi @jamesosborne,

Thanks so much for the continued follow-up. I do have a couple of extensions installed & active: 1Password, Grammarly for Safari, and Honey. There’s a fourth extension installed, but not active, for Parallels Desktop (it’s an “Open In I.E.” option that I don’t use).

I tried de-activating all three active extensions and testing… same issue.

I also checked my “Experimental Features” list… and couldn’t tell if I’d changed anything there, so I used the “Reset All To Defaults” option and tested again. Same issue. Get the errors when trying to view Site Kit data in the Main WP Dashboard or in Site Kit’s Dashboard.

Let me know if there’s anything more specific I can try.

Thanks!

Many thanks for sharing this information, greatly appreciated. We’ve ben unsuccessful so far in recreating the same experience.

If you happen to have a Safari browser installed on another Mac which you may have, or another device it would be great to know if the same occurs when logging into Site Kit from on of those devices.

And one other test that may be useful is to know whether the same occurs with only the Search Console module active. You can temporarily disconnect the other connected modules within Site Kit via “Site Kit > Settings > Connected Serviced > Edit“. If this does occur with only the Search Console module active.

Thank you!

Hi James. Tested on my other laptop (also MacOS Mojave v10.14.6 with Safari v14.1 (14611.1.21.161.7)) and it has the exact same problem.

It works fine in Safari on iOS.

I tried disabling all Site Kit features other than Search Console and had the exact same error:

Failed to initialize NumberFormat since used feature is not supported in the linked ICU version

Many thanks for sharing the additional insights, which I’ll add to the related GitHub issue. We’ll continue to test from our side and I’ll let you know here of any updates. Thanks again!
