woo commerce HTTP ERROR 500

I just upgraded to woocommerce 3.6.0 and now I am getting HTTP ERROR 500 on some of my sites. I clicked the upgrade button and then clicked off the page. I think it was not finished and caused the issue.
I have several sites in woocommerce and some of them are working and others are not.
I tried updating wordpress again and the network database again, but no help.
I checked out other posts with the same issue and tried disabling plugins, but it has been a long time since I messed with any of this and it did not help. My best guess is that the woocommerce upgrade did not finish and I don’t see a update again woocommerce button. Any help would be appreciated.
