Upgrade 3.70 - 4.00 Application startup exception seven spikes core

Hi

I upgraded a site from 3.70 to 4.00.

Its a single shop.

Everything runs fine until I push Update plugin list then I get this error(and I need to restart server to solve):

Application startup exception: System exception:Plugin 'seven spikes core' Acces to path '......./plugins/bin/sevenspikes.nop.plugins.core.dll' is denied.

In warnings all the right permissions are "green".

The right permissions are granted to all files and folders.

What can I check?

Hello Tommy,

The upload plugins and themes from the administration functionality firstly delete the plugin/theme you are trying to upload from your store if it is present in your files before uploading the new version. It seems that the .dll file of the Core plugin is locked or still used by some process while the application is trying to delete it.

We've and some of our clients have encountered such issues when using Azure to host their stores. This is why we've written the following article.
This article applies only if you are using Azure. If you are not using Azure I will ask you to submit a ticket with access to your server (place where your store is hosted) so we can further investigate this issue.

Hello Anton,

It´s not running on Azure.

I will make a ticket tomorrow :-)
