Install new plugin disabled with JobRoller
I just installed JobRoller on
WP v 4.5.2. Some JobRoller setting disables the ability to view the "Update" Wordpress tab in the Dashboard (update-core.php returns a blank page). The same thing happens under the Plugins tab (plugins.php) when you select "Installed Plugins". Selecting the "Add New" link (plugins-install.php) under the Plugins tab returns a 500 error.
I had installed this a view days ago and experienced the same thing so I completely removed/reinstalled thinking it was some file I deleted. The program had been working without a hitch until I reconfigured some settings under the JobRoller tab (not sure which ones though) and/or installing other plugins (although I'm unable to reach the plugins page to deactivate and test them.
