After 1.9.0 update, I have no access to plugin.php, dashboard updates or UpdraftPlus settings page. All I get is a blank page. I tried deleting the plugin and UD folder in wp_content via hosting control panel, so that I could try to reinstall (thinking the update went bad). In my Admin panel, it still says I have one plugin (UD) to update. If I try to install via "add new", search for UD, it denotes "update now" rather than install. I have also tried downloading the plugin and uploading through "add new" to no avail. Please assist with uninstall/reinstall instructions.
Thank you.
