The admin panel does not work after updating to version 8.

[Tevildo]

Hello. Tell me how to solve the problem, updated the site 1.7 to version 8. But after that, the admin panel does not work. It gives an error

The service "prestashop.adapter.news.circuit_breaker.settings" has a dependency on a non-existent service "prestashop.core.circuit_breaker.guzzle.cache_subscriber".

Please tell me how to solve this problem. Already updated both through 1-Click Upgrade and manually, the problem is the same.

Use a back up and restore the old shop.

Well if a hosting switches witout telling you its time to saddle the horses and look for another host. On a VPS you can freeze the PHP version which gives you time to renew your shop.

Here is the solution if someone else have again this issue.

You must :
* Delete your src folder
* Unzip src folder from your 8.X installation

This service no more exist in PS8+
