Can’t auto upgrade plugins

Have you tried disabling (or removing totally) the plugin you mention on the other thread you just posted?

yes, it was happening before I installed that plugin. could it be another plugin that’s causing me to be unable to auto upgrade?

Possible I suppose. If in doubt, de-activate your plugins. Not a bad rule of thumb to start your troubleshooting with!!
