Loaded NPM package to test PR.
After there were changes in the code, of course I needed the new NPM package.
Usually (before new NPM) I load a Nightly, whatever works. You can see the menus above/below, but the page is broken.

Message: Call to undefined method Joomla\Plugin\Behaviour\Versionable\Extension\Versionable::setApplication()

Can I find this plugin in DB to delete it?

go to administrator/cache
delete the file autoload_psr4.php
reload the web page and the file will be rebuilt correc;tly

Thanks @brianteeman but:

Had similar in the past (another PR) - the one with the autoload_psr4.php file. Am almost sure it was a different error message - the deletion and reload was successful at that time.

Now: Had successfully deleted. Newly invoked. But still the message. Front end and back end.

@ChristineWk Could be because your installation, for some reasons, does not contain the changes from this PR #38060 . So I guess the easiest way would be download and install 4.2 nightly build to get rid of the error.

@joomdonation: Thanks for investigating.

Am sure the changes of PR 38060 were not included. Because: Think it was unfortunately J 4.1.6-dev, not 4.2.
I can no longer go to the backend.

That means I can only try to install a J 4.2 Nightly over it via FTP and then try to repair the DB.

OK @ChristineWk . I'm unsure if it works but hope you can get the site recovered.

@joomdonation

Will try it tomorrow. Don't know at the moment. I haven't dared yet.

Question: Can the reason be that the NPM package included this PR? #38060?

@ChristineWk I'm unsure. I only guessed the problem base on the error message. It says that setApplication method does not exist and that method was introduced in the mentioned PR

You might want to try to replace the file libraries/src/Plugin/CMSPlugin.php in your Joomla installation with the code from 4.2 branch https://github.com/joomla/joomla-cms/blob/4.2-dev/libraries/src/Plugin/CMSPlugin.php to see if it solves the issue. I'm afraid not, but could try.

a) First I tried swapping file libraries/src/Plugin/CMSPlugin.php. Not successful.

b) 4.2 Nightly Fully installed/unpacked/loaded etc via FTP.
Of course without /installation, but keeping configuration.php.
Took some hours (Server not fast ...)
The result was that I got the (known) famous "whoops, something went wrong error 500 for hours ...."

c) Then I checked and tried many things, etc. I can't describe everything now....

d) Then I got this message (again):
Class 'Joomla\Plugin\Behavior\Taggable\Extension\Taggable' not found

e) administrator/cache: deleted the autoload_psr4.php. = OK.

Status present:
Frontend: menus rows are shown, but:
Call to undefined method Joomla\Component\Tags\Site\Helper\RouteHelper::getComponentTagRoute()

Backend: (Instead of Login Mask): Unsatisfied dependency "hotkeys.js" for an asset "script" of type "script"

So, the above was just the short version....
Maybe I'll activate the call stack (via DB) later, .... don't know yet. Is too much for me now.
At the moment, guess I give up...

This pull requests has been automatically converted to the PSR-12 coding standard.

@ChristineWk The PR has been updated meanwhile, and new packages have been built by drone, so maybe you can give it again a try.

@richard67 had to completely delete my test page on 30.06. (after many various checks etc. ). will think about it with new 4.2-dev...

Tried again with NPM Package:

No focus ring.

Database Version shows: 4.2.0-2022-06-22

You have used your keybpard to tab to the navigation buttoons?

When you click, focus flickers short. = OK.

With the tab: a bit different than the screenshot in instructions above. is that correct now?

I have tested this item ? unsuccessfully on 45e4048

same results as @ChristineWk which is not the intention of this PR

The problem is because of the scss in bootstrap _pagination.scss
&:focus { z-index: 3; color: $pagination-focus-color; background-color: $pagination-focus-bg; outline: $pagination-focus-outline; box-shadow: $pagination-focus-box-shadow; }

As you can see there is a box-shadow being set here and this PR just adds another box-shadow on a different class. Then because of the z-index you get the reported issue.

Thanks for testing. Will have to work on it when I have time and close for now.

I’ve reopened the issue.
