Intall Admin Error !

[satarzai_ataur]

I'm new in magento

I installed magento v2.2.2. So I use PLAZA THEME (Shopro). I have a problem with the administration page when I go to my website (in localhost).

The problem is that when I go to my site http://localhost/8000 the site works well (I see the luma theme).

But when I go to my admin site http://localhost/8000 I have this problem...

I searched on the internet for the problem but I can't find any solution to the problem, it's very embarrassing for me.

Here you can see my var/report/logfile (309821993744).

{"0":"Class Plazathemes\Blog\Observer\PredispathAdminActionControllerObserver does not exist","1":"#0

The problem is very long, so here is the complete problem : https://pastebin.com/kk6yYefA

I hope I've made myself clear.

thank you,

Hi @satarzai_ataur,

Did you followed all the installation steps?

Did you executed the compile command?

bin/magento setup:di:compile

I've checked the theme page and it seems to be comaptible with 2.2.2 but maybe you should ask the vendor for support since the theme is paid.
