[4.x]: Deleting Sites and Site-Group throws an "Undefined array key 2" error, when trying to open an entry.

[hhentschel]

What happened?

Description

I updated to latest version (4.7.2.1) and deleted some sites and one site group I don't need anymore.
I also changed site name handles.
After that, I cannot open entries in the control panel. Seems that Site ID are mixed up or something.
It gives a php error: Undefined array key 2

Steps to reproduce

1. Deleting Site and changing site handle names

I tried to resave entries via cli but get the same error there.

Could solve the issue myself.
I am not sure if this is the expected order to delete sites, but before deleting a site i had to disable/set inactive a site within the setting of a structure. Then wait that the entries are saved again and then go to the sites settings and delete a site.

Hey, I have the same issue - when the site removal is applied via project config. I think it only applies to pages that have matrix on them. Would be happy about some hints how to tackle this, as I need to apply this change via project-config

[brandonkelly]

Sorry, missed your last response @hhentschel. Thanks for posting that.

Believe I just fixed this for the next releases. @maxstrebel you can test by changing your craftcms/cms requirement in composer.json to one of the following values:

• 4.x-dev as 4.9.6 (Craft 4.9)
• 4.10.x-dev as 4.10.0-beta.1 (Craft 4.10 beta)
• 5.x-dev as 5.1.8 (Craft 5.1)
• 5.2.x-dev as 5.2.0-beta.1 ^5.2.0-beta.2 (Craft 5.2 beta)

Then run composer update.

[maxstrebel]

Thanks @brandonkelly – that seems to do the job 🙏

[brandonkelly]

Great, thanks for confirming!

[brandonkelly]

Craft 4.9.7 and 5.1.9 are out now with that fix.

@brandonkelly

Hey Brandon - thank you for doing the fix so quickly. 
I work on the project with @maxstrebel.

Unfortunately I noticed the following behaviour:

• I work on the clean version pulled from production updated to craft 4.6.9.
• Download database from production and import it with ddev import-db
• I go to Utilities -> Project Config -> Click “reapply everything”
• Check git status and I can see that a big number of yaml files was altered. Many sections and fields are removed.

If I do the following:

• I work on the clean version pulled from production updated to craft 4.6.9.
• Download database from production and import it with ddev import-db
• Execute craft up
• Checking git status -> no changes to yaml files, so as expected
• BUT as soon as I change anything in the backend. (In my case added a new Category field), the same unexpected altered yaml files appear.

Why I think it can be related to that issue ->

If I do the following:

• discard the unwanted changes via git
• Run craft up

I end up with the same php error: Undefined array key 1 related to the sites.

I have a hard time making sense of it. Do you think this issue could be related?

[maxstrebel]

I think we might have committed to early. The generation of the YAML files takes very long in this project. I just thought I can reproduce but after a minute the deleted files were recreated. We will test this together tomorrow morning and write again.
