Once a feed is created it gives the following message:
"The feed has been created successfully.", but the feeds page is still empty.
The plugin is network enabled, performed Plugin conflict test, ie disabled all the network activated plugin, and also the plugins in the main site, still the same issue. Enabled debug mode, but it isn't generating any log files, which is really odd. Trying to make this work in the main site. Not able to replicate such an issue in other system.
