Plesk Onyx 17.5 - Wordpress extension "checking for updates" hung up says "in progress"

I have a PLESK 17.5 Onyx server. On the Extension - Wordpress ToolKit you can check for updates. I ran this and it worked fine and still does.... BUT it is hung up "checking for updates" and has a spinning wheel saying "in progress." I have restarted the server. I have stopped and started the Wordpress Tool Kit. I have detached and reattached all of the 6 Wordpress websites I have on the server. STILL hung up and saying "in progress" and checking for updates. I need someone to fix - clear out the command that is telling it to check for updates. Should be very simple. You might could just tell me how to do it and I could take care of it and of course PAY you for your information. Thanks LEon
