@DGT41
Please check this urgently as RC is tomorrow

[dgrammatiko]

@infograf768 it seems reasonable but I cannot test it at the moment

[laoneo]

I think you need to make sure that the core js file is loaded.

[brianteeman]

This was urgent in 2017 - has it been fixed elsewhere?

[farzadtaheri]

@brianteeman, unfortunately not yet!

[coolcat-creations]

Is this PR still to test?

@Quy @brianteeman
I just started with Github and my original language is not English
So I may be misunderstood
I wrote the PR, which I tested it by myself and it works perfectly and solves the issue.
Do I need to do anything else to merage this PR? please Guide Me.

[laoneo]

I'v posted it in the public testing glip group. Maybe we will get some testers.

[laoneo]

Change looks fine for me.

@laoneo I've just tested this PR, but not really successful regarding the described issue.

Regardless if the PR is applied or not, and regardless is the backend language is Persian or English (GB), the published date changes when changing category of an article if the website time zone in Global Configuration is set to something else than UTC, and it doesn't change when the website time zone is UTC (without a time zone for the user set in all these cases).

This seems to be solved by PR #28596 instead (have to test that again with Persian backend language).

But this PR here seems to fix another issue: When the backend language is Persian and the PR is not applied and I change the category of an article, the toolbar and top menu bar disappear with the page reaload.

When the PR is applied this doesn't happen. When backend language is English (GB), this also doesn't happen.

Can someone check and replicate my findings?

[richard67]

With both PRs #28596 and this one here applied together, all is fine with any website time zone and with any backend language.

[infograf768]

Can someone check and replicate my findings?

I confirm.
The errror is

It is solved by this PR.
