FAQ relevant for: all Academy versions

Hi all,

Support for Manifest V2 has officially been disabled in Google Chrome, which means the Elasticsearch Head Chrome extension is no longer functioning properly on the VDIs.

When you try to add the Elasticsearch Head Chrome extension you may see the following error:

Error Message: This extension was turned off because it is no longer supported

"This extension was turned off because it is no longer supported"

or this error:

Error message: Cannot install extension because it uses an unsupported manifest version. Could not load manifest.

"Cannot install extension because it uses an unsupported manifest version. Could not load manifest."

We are looking into ways we can resolve this issue, however for now we have a workaround to get the extension working.

Error Workaround

Here are the steps you can follow to work around this error:

Step 1: Navigate to chrome://flags/ in the Chrome browser:

Step 2: Disable the following settings:

  • Extension Manifest V2 Deprecation Warning Stage

  • Extension Manifest V2 Deprecation Disabled Stage

  • Extension Manifest V2 Deprecation Unsupported Stage

Alternatively on some versions the setting may appear as the following:

  •  Allow legacy extension manifest versions 

In this case you will need to enable the setting as seen above.

Step 3: Restart Chrome.

Step 4: Re-add the Elasticsearch Head Chrome extension. This comment details how to add the extension to Chrome.

You should now be able to use the Elasticsearch Head Chrome extension as normal!

 

Apologies for the inconvenience, I hope this helps!

    i found a guide,
    you have to search "m1" and enable "temporary unexpire M138 flags" and "temporary unexpire M139 flags". restart your chrome then you would be able to search "mv2" and allow legacy extensions. restart again and you should be good to go. works for chrome v140.

    Hi Sian_Ayres​ , thank you for capturing the errors and providing the workarounds. I accidentally had removed my ElasticHead extension and now am unable to add it back due to this error: Error message: Cannot install extension because it uses an unsupported manifest version. Could not load manifest.

    I have tried using the troubleshooting steps as you have mentioned, however, inside the chrome://flags/#extension-manifest-v2-deprecation-warning I am unable to find the mentioned flags:

    • Extension Manifest V2 Deprecation Warning Stage
    • Extension Manifest V2 Deprecation Disabled Stage
    • Extension Manifest V2 Deprecation Unsupported Stage

    The only Flag close to above was this: Allow legacy extension manifest versions

    I have tried disabling the above flag but is of not much use. Any help would be appreciated. Thanks.

    • Extension Manifest V2 Deprecation Disabled Stage

    Step 1: Navigate to chrome://flags/#extension-manifest-v2-deprecation-warning in the Chrome browser:

    Step 2: Type ‘M1’ in the search bar - you should be presented with two options:

    • ‘Temporarily unexpire M138 flags’
    • ‘Temporarily unexpire M139 flags’

    Select ‘Enabled’ for both settings, then restart the Chrome browser.

    Step 3: Type ‘Extension’ in the search bar and scroll to the bottom of the search results until you find the setting ‘Allow legacy extension manifest versions’.

    Step 4 (optional): In some cases, you may need to re-add the Elasticsearch Head Chrome extension. This comment details how to add the extension to Chrome.

    I hope this helps!

      Hi navalsudhakar​ 

      May I ask for your permission to access your VDI? I can take a look inside and hopefully identify the issue for you.

        Hi Oliver, 
        Could you please access my VDI and help me solve the same issue? I wanted to add the extension once again (Step 4 above) but it is impossible.
