Application startup exception: System.Exception: Plugin 'Credit Card'. Access to the path '\Plugins\bin\Nop.Plugin.Payments.BrainTree.dll' is denied

Morning All,

Hope somebody can help, having a serious problem with a the Braintree Plugin, keep getting the below error, which brings the whole nopCommerce 4.0 site crashing down, uninstall the plugin and all is fine, reinstall and is fine for a day or so, but the same cycle keeps happening, As Braintree is my man payment provider this is quite a serious issue, can anybody shed any light, I use the NO SOURCE build of nopCommerce.

Many thanks

Nick

Found a similar issue here, have applied the fix to the Application Pool, will let everybody know how it goes https://goo.gl/7PBM5w

Changing the Application Pool settings didn't work for me, anybody with any more suggestions?

See if this helps

Which version of nopcommerce are you using.

If you are using nopcommerce 4.10 than it is shadow copy problem.

You can find solution from here https://www.nopcommerce.com/boards/t/49851/serious-iis-application-pool-recycling-bugdesign-flaw.aspx?p=3#199596.

Hope you will understand..!!

I had the same issue and the problem was about writing permission on the folder. Hope this could help

Thanks for your reply, changing the permissions seemed to of solved the problem

Deleting the Plugin folder worked for me!
