I cannot figure out why it prints those errors, admin dashboard does not print any error.
Please help!

You have meesed something with config or modules I think.
Try to Clear all Modification in admin, And what do you mean by "Problem when moving server and upgrading"?

You should try to contact any developer for support or post in Community forum,
this is not related to Opencart source :(

The website was on a shared hosting, now it is on VPS. I had exported MySQL and saved website on my local machine. I installed newly Opencart on my VPS and then imported the DB also uploaded the rest of files to the VPS.

[arnisjuraga]

Did You changed opencart version too? I mean - Shared hosting had older version as the new one?

[narektigranyan]

Yes, it had older version, for VPS I downloaded the most recent version

[narektigranyan]

Also I deleted the whole modifications in Extension in admin panel

[arnisjuraga]

I see - at first, you must have the same version on VPS, if you are using any custom code\modules\extensions\theme! Latest Opencart could bet not be compatible with your site at all.

So

1. Try to find and install the same Opencart version
2. contact any Dev support, if you still have issues :(

[narektigranyan]

In Modifications it dumped some error log. can it be usefull?

[narektigranyan]

Thank you very much! I will try to install the same version
