I can not duplicate any issue you have reported.
Those games work fine for me without any lag.

You should update your arcade to the latest version.
Although this will not solve your issue it will implement many fixes & updates.

Try a different browser.

The arcade is accessed via the index therefore errors can sometimes be caused by other mods or edits even though they occur during an arcade action.

The error shown from this line of Subs.php:
/www/xxxx/xxxx/xxxxx/Sources/Subs.php (Line 6833)

.. seems to be from another mod because by default that line number exceeds the default file length of Subs.php in both SMF branches.

In my opinion it appears you are having some sort of cache issue.
Try clearing the cache and/or using a different available accelerator.
 

You can go to Arcade -> Maintenance & opt "Fix Category Game Counts" then click on complete action.
This will fix the issue you reported however I will add it to the pending list so it does this automatically after uninstalling games.

The settings for that are in your profile.
You can choose to receive a notification when anyone beats a score or if they only beat your score.
 

Lots of the older attachments got lost a while back.
I will have to make a new one and update the initial post.
Keep checking this thread as I should have time to do it later this week.

This block was made a long time ago.
It has been fixed with the changeable options in the initial commented array.

Let me know if it works as expected.

You were showing screenshots of this site.
At that time this site was not updated to the latest release.
In fact it was reverted back to v1.24 beta2 at its onset due to some behavioral testing.

However, I just updated this site to v1.24 stable.
How does it look now?

Eh Portal v1.24 has been released which includes adjustments for SMF 2.1-RC1.

Eh Portal v1.24

Please report any feedback and/or bugs in this support board.

The package is available in the download section.

Yes, beta testers had recently reported a few needed changes.
I will release an update within a day.
Thanks.

Do you want 4 per row or just 4 in total?

Keep a running count & use a modulus operator.
When your operator does not equal zero have the parent div as block else make it inline.

Please note that the Arcade remembers each member's game type preference in the database.
This means if you want it to show all game types then you need to select that option.
It will record whatever option was previously selected.

I'll try testing some of his newer releases.
If he is still using the IBP submit it should work but perhaps he changed it.

[edit..]

Actually the error shows IBP submit.
It should be working with v 2.56.12 as I adjusted it to accept html5 games as ibp save type.
I will likely work on it later this week when I am off work.
Thanks for the report.
