its not the plugin ..As an admin, what is the link that you see when you hover the options tab?
As a subscriber, I see:
https://www.carlocab.com/wp-admin/admin.php?page=feedcount.php
Thats NOT a normal link for that tab.
Ive looked at a 2.0.11, a 2.3.3 and a 2.5 install none of them even show that tab to subscribers, much less make that tab, that link.
the options tab ought to point to https://www.carlocab.com/wp-admin/options-general.php
.. which by the way, when I load in my browser, tells me, correctly, that I dont have access.
I also just uploaded that plugin to yet another 2.3.3 install, created a subsc. acct, logged out, and logged in as the lesser person — I cant duplicate whats going on on your site.
I suggest, at the very least, deleting all the core WP files from your wp-admin directory (including wp-admin/includes/), and uploading fresh copies.
And are you using any plugins that make modifications to the admin area?

The other thing that suggests that this is your install and not a singular plugin issue is that you seemingly see it with 2 plugins.
I didnt hunt around for the other.. didnt see so maybe you have disabled it. Either way, plugins are typically written to take advantage of WP’s built in ability to keep users where they belong, and that you have 2 anomalies suggests its the site.
If you like, after you re-uploads those files, I’ll take another peek, or you can (make a test subscriber acct) ?? Just clear your cache first, and obviously make sure you login as a subsc. and not an admin
