Hi @danharper83
Please try clearing static content in your store. This issue looks like it relates to it.

@danharper83: do you have minifying JS enabled?
If yes: then you are running into a new bug introduced in 2.2.4, because the now-included-by-default Klarna modules have a bug in them which causes the tinymce editor to not work properly when minifying JS is enabled.
It has already been reported at the end of an old issue, so it's good to keep this issue open, until Klarna prepares an update for their modules and Magento releases them on their repo, so we can update them using composer.

For now, easy fix: disable the Klarna modules if you aren't using them :)

I disabled Klarna and then cleared the static content but still have the problem. Where do I find the JS minification setting?

[seo99ita]

I solved the problem by following these and then following these too, which I fully endorse.
Now everything works correctly.

@danharper83: this works for me (started from a clean 2.2.4 project running in production mode):

bin/magento module:disable Klarna_Kp Klarna_Ordermanagement Klarna_Core
bin/magento deploy:mode:set production

I wouldn't recommend following the first link by @seo99ita though, that's not the right way to go.
I agree with the second link though, good article by Jisse!

[danharper83]

I didn't spot the other Klarna modules, once disabled and re-deployed all works fine 👍

Can be marked as resolved I guess, is this logged with Klarna somewhere so we can link the issues?

[hostep]

I'd leave it open until fixed.

No idea if someone reported it to Klarna (I didn't) or even how to report it, I've opened an issue for the doc team requesting for contact information for those new Core Bundled Extensions: https://github.com/magento/devdocs/issues/1961

[matin73]

bin/magento module:disable Klarna_Kp Klarna_Ordermanagement Klarna_Core worked for me

[hostep]

Updating the Klarna modules to the latest version using composer seems to fix the issue, at least I don't see any <minify_exclude> entries anymore in those modules, so I assume it should be fixed.

Can someone confirm, so we can close this issue?

[danharper83]

Tested and it seems to be fixed in 2.2.5

[hostep]

Thanks @danharper83. @LSERRE also confirmed in https://github.com/magento/magento2/issues/11577#issuecomment-401840977, so let's close this issue as it is fixed in the latest version of the Klarna module.

Why do we need these modules anyway?

[drinkingsouls]

I also have this problem in fresh install. Disabled Klarna but the issue persists.

@drinkingsouls: it might help if you read the entire thread of https://github.com/magento/magento2/issues/11577, there are some useful comments there which might steer you in the right direction. Good luck! :)
