THANK YOU! Brilliant suggestion.

I installed it as you suggested (via the admin dashboard as opposed to uploading the zip version manually) and it WORKS!

And thanx for the faster-than-light answers. You helped me very much.

Thanx for a quick reply.

Downloaded again and installed (and switched off all other plugins just in case). Still get this upon activation:
Warning: require(/zlomnik2/wp-content/plugins/wp-rss-aggregator/vendor/composer/ClassLoader.php): failed to open stream: No such file or directory in /zlomnik2/wp-content/plugins/wp-rss-aggregator/vendor/composer/autoload_real.php on line 12

I installed the plugin on another website of mine as well (just to see what would happen) and got the exact same issue.
