We installed the Simple RSS Feed module and Joomla (3.8.7) said installation was successful. However when we go to Joomla Modules, the newly installed module does not appear. We cleared site cache, signed out and back in, but nothing.

Never mind—would help to create a syndicated module :-( I think I need a vacation

What was the issue Paul,
We all need a vacation :)

Krikor~

I was looking for Simple RSS Feed under 'modules' and of course it wasn't there—LOL! Once I created a new module and selected syndicated feed, "abracadabra" it appeared!

Some days . . .

It happens Paul...
It has happened to me more times that I like to admit
