can’t access dashboard after migrating

Hello,

After trying for some hours of googling and tries I took the decision to ask for help here cause i’m kinda desperate ??

I transfered a single multisite subdomain blog (site1.mysite.com) to his own domain (site1.com)

I made sure I had the latest wp version before migrating. I ftp uploaded the upload/plugins and themes folders to the new domain.

I took the wp_prefix_siteid tables from phpmyadmin
added them to the new db and changed prefix, search and replace all urls and uploads paths

The website on the frontend has no issues ( https://annalisamantovani.com )

But I can’t access the wp dashboard anymore.

If i try to access /wp-admin i get “Sorry, you are not allowed to access this page.” message.

If i login using /wp-login path I can login but i can only see the frontend, no possibilities to go in the backend, It’s like i’m a normal user. I checked 10 times and the user i have in the database has adminitrator role. ( wp_capabilities
a:1:{s:13:”administrator”;b:1;}; wp_user_level: 10).

I tried renaming plugins/themes via ftp but no luck. I tried clearing cache/cookies.

I am kinda lost on what I am supposed to do.

Any help is really appreciated.

Thank you for your time.
