My Revive Ad Server installation has been running fine for months, but suddenly today ad delivery was not working. After some investigation it turns out there are no plugins installed (the plugins section in admin is completely empty), so I tried to follow this guide to reinstall the plugins. However when I try to install a plugin I get this error:
Failed to find package definition file /var/www/banner.anon.com/docs/var/www/banner.anon.com/docs/var/tmpopenX3rdPartyServers.xml.xml Failed to parse the plugin definition openX3rdPartyServers.xml The uploaded file did not pass security check The uploaded file openX3rdPartyServers.zip was not unpacked
Looking at the first line in the error message the path looks like it is duplicated, but I'm not sure if that is related to the problem. Also I'm not able to locate tmpopenX3rdPartyServers.xml anywhere.
