[SOLVED] Opencart 3.0.4.0 white blank page after installing theme

Opencart works until I have installed Amelia theme from opencart. I have report this to support but nothing happend for 2 days.
I get blank white page in index page or admin page
http://sellyour3d.com
I use php 8.0
apache 2.4.62
all browsers is the same
I uploaded amelia files to opencart folder and overwrite all files all have apache permission.
server is rockylinux 9 and all is updated apache, mariadb and php. And no errors in apache log file.
I also cleared all cache in all opencart folders.
All files have right permissions.
I even backup files before I upload and overwrite existing files and when I restore backup files to opencar folder it is the same.
I have now added this to index page in admin folder
ini_set('display_errors',1);
error_reporting(E_ALL);
and now I get error on that page.

Fatal error: Uncaught Error: Class "Openbay" not found in /var/www/storage/modification/admin/controller/startup/startup.php:63 Stack trace: #0 /var/www/storage/modification/system/engine/action.php(79): ControllerStartupStartup->index() #1 /var/www/html/opencart/system/engine/router.php(67): Action->execute() #2 /var/www/html/opencart/system/engine/router.php(46): Router->execute() #3 /var/www/html/opencart/system/framework.php(179): Router->dispatch() #4 /var/www/html/opencart/system/startup.php(104): require_once('...') #5 /var/www/html/opencart/admin/index.php(21): start() #6 {main} thrown in /var/www/storage/modification/admin/controller/startup/startup.php on line 63

OpenBay was removed in 3.0.3.6. This suggests your admin/controller/startup/startup.php file is from an old version or you have upgraded, but not upgraded your storage directory or deleted the contents of storage/modification/ and refreshed you modifications.

My installation was fresh all over again with 3.0.4.0

You have not done a proper fresh install of OpenCart 3.0.4.0. Your admin/controller/startup/sass.php is from an older version!

If you are using the [url=https://www.opencart.com/index.php?rout ... n_id=34619]Amelia Theme then you have to contact its author for support.

Sorry I don't know how can that be?
Because I never even before installed older than 3.0.3.8
And I have installed purpletree multi vendor extensions and cookie extension and nothing else.
And exactly that theme and I already contacted author but no response.
Is it possible that is messing with my installation?

Then why don't you contact these extension vendors? Especially the multivendor one from PurpleTree. Quite often 3rd party extensions are of poor quality and not properly tested.

I will contact purpletree, I bought this extension because it was top rated.
What I did now.
I have installed another fresh installation of opencart 3.0.4.0
And copied from that installation a storage folder to its place.
And the same a problem here are errors I get now.
Error is about Openbay, what that is and how is related to opencart?

Where are you downloading 3.0.4.0 from?

Line 62 of admin/controller/startup/startup.php does not try to create an OpenBay class on 3.0.4.0.
https://github.com/opencart/opencart/bl ... up.php#L62

But older versions did.

I bought this extension [you mean theme] because it was top rated.

Probably fake reviews unfortunately.

You should use a CSS-only theme like one of ours: https://www.antropy.co.uk/opencart-serv ... me-builds/

Also, Openbay is a discontinued product and won't work on OpenCart 3.0.4.0. See also this forum post.

I have installed opencart again and now it is ok.

Ok I will check those themes and if there is something nice I will buy it.
