Hello
Use Joomla 3.9.21 with PHP 7.3 and k2 component V 2.9
I have 2 sites on the same server that I updated today for Joomla 3.9.21, I'm from Brazil

First I upgraded to Joomla 3.9.20 and noticed that this was the case, then I decided to upgrade to 3.9.21 and the exact same problem occurred below

When trying to publish articles via e-mail, I have to set the time for four (4) hours before (that is, if I post at 5 pm I have to post the article at 1 pm to publish immediately) to be aired immediately otherwise it will not go on air .
It seems like an exclusive team problem only with the

I tested publishing the articles via the Joomla Editor v3.9.21, then there is no problem, the article goes live immediately.

More details to see if it helps:
- The server has the right time
- The configuration of Joomla, Global / Server is correct, this is like "Sao Paulo" (Brazil South America) which is my region.
- In the Editor of k2 when opening in New to post a new article the date that appears is correct, exactly with the time of the moment. But when saving the article it doesn't go on the air, the article is saved, but it doesn't go on the air, only if I go back in the article and go back to the schedule for four (4) hours ago.

Does anyone know why this occurs with the k2 component?

I look forward to a possible help

Thank you

Hello!
All well?

I just followed your advice and upgraded to K2 VERSION 2.10.3 on both sites.
This problem really corrected on both sites, now this is ok.

1 NEW PROBLEM: Only one of them has a problem with the Image part of not finding the Image Database that you have on the site, the Image button / search server
It seems that the link searches for images on the server is not finding the images.
Do you have any idea what I can do?

As for my region it is Brazil and there is a difference of only 3 hours, but the problem that was in the country is the difference of 4 hours as I said.

I look forward to a FeedBack on this image link?

Awaiting

Thank you
Cheers
Much Success

Hello

Thanks for the tips, but come on

Our server is dedicated and exclusive to our website.
Some values of our php version 7.3
max_execution_time 300
post_max_size 128M
upload_max_filesize 128M
memory_limit 256M

Do you think I should change any of these values?

Now among what you reported, there is a detail, we have many images, as it is a news site and there are more than 200 thousand news on it and I believe that around 20 thousand images

A question? When this type of error occurs, can I install a previous version, like k2 version 2.10.2 or version.2.10.1 on top of version 2.10.3?

I await your analysis

Thank you
Success always

Hello

Just a correction:
My apologies
When I say that it has 20,000 images it is not in the Joomla image folder but in the K2 folder, the vast majority are images of the same.
Does that influence anything?

As I understand it, you advise me to increase the memory_limit from 256M to 512M am I correct?

Thank you
Success always
