Perhaps it is related to the theme you are using, I would like to check this out...

I'm using the default theme on the test server. I also use the default theme to admin the live forum.

Can I private message you a link to the test forum?  You can see it happening there. I upgraded back to the current version of TP and it immediately broke the columns again.

Just setup 3 blocks in my upper panel here: https://test.fjr-club.nl/index.php and it works as it should...

Ok, so I went through the trouble of removing an old version of TP from my test server. I made sure the database was completely cleaned out of any TP entries.

I upgraded the test server to the latest version of smf (2.1.2) and then installed the latest version of TP (2.2.2)

I set the upper panel up to display 3 columns like I had on my live forum. I created 3 blocks in the upper panel.

The result is the same. It doesn't display the blocks in 3 columns. It displays them in a single row off to the left side of the panel.

I haven't tried to do this in any of the other panels so I don't know if I would see the same results.


edit: to add, I reverted my test forum back to 2.2.1 and the blocks displayed in a horizontal row as expected.

Is it safe to downgrade from 2.2.2 to 2.2.1? 

Hi,

I have found out, that if I add an block, which actually works, I can also see the block section to administrate. Once I delete this block again, I again run into 502 error.

What exactly do you need in terms of the environment data?

PHP version: 7.4.29
NGINX
running on a quite sufficient vserver.

So I added another block which I just did not activate, hence I can access the block administration again, but of course this is not the intended state

Thanks in advance and Kind Regards
Christian

I tried that and got no love.  I'll post back in a few minutes. I managed to get it to show the blocks in the 3 columns, but I had to change the way they were displayed to grid and set the size to 33%.

I've never had to do that before so I'm not sure why it would act that way now. 

I changed it back to 3 columns and it went right back to displaying the blocks in a 1 column row.

For now, until I can get this figured out, the grid display works? 

If I had more time I would set up a test server and try this from scratch.  I would imagine that this is more difficult to trouble shoot on an upgraded install than on a fresh.
