Magento Upgrade from 2.3 to 2.3.1 Issue via CLI or script: script errors appearing when loading

[icewing02]

Hi There,

Just did an update using the docs: https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html

The installation process did not encounter any error.

Except, when loading the website, it took too long to load (and actually loads forever) with elements slowly appearing after almost a minute but still not done after that. I checked the console and after stopping the loading, turns out, several scripts are not loading (see attached screenshot). The error could pile up if loading is not manually stopped.

What did I miss here? I tried both CLI and script, and both has the same results.

Thanks,

Jay

Upgrading 2.3 to 2.3.1 via composer disabled all the caches on my system and made it use 100% cpu until it restarted and caches re-enabled.

Might be same issue.

Hi Paul,

It worked, Thanks!

In my case, just the disabling of all caches before proceeding with the update, then re-enabling after the whole update process (https://devdocs.magento.com/guides/v2.3/comp-mgr/cli/cli-upgrade.html) did the trick.

Cheers!
