WordPress Toolkit: 'plugin list' is not a registered wp command

[Eleshar]

I'm attempting to utilize the WordPress Toolkit. After clicking scan on a webspace with WordPress installed the panel returns the error "'plugin list' is not a registered wp command. See 'wp help'.".

I've tried it on a few servers that has the WordPress Toolkit installed, but they all return the same error.

Any ideas as the what the issue might be?

Thank you in advance.

I can't found any mentions of this error in any our internal and external sources. It looks strange for me. Looks like that you have some kind of customization. Therefore I can only recommend to create a request to support team to do in-depth investigation to find the reason and to fix it. Please create a ticket to support at https://www.odin.com/support/request/ .
You may have free support, please check what kind of Plesk license you use for available support options at http://kb.odin.com/en/121580 .
If there’s no free support in your case, you can order Plesk per-incident support at http://www.odin.com/support/buy-support/ Support team will contact you as soon as purchase is processed, and they will do the best to resolve it.
If it is found that your problem was caused by product bug w/o available solution or workaround from Parallels, then your purchase will be re-funded.
