Okay, so I've Installed MultiSite and WordPress MU Domain Mapping plugin.
Finally got Pageok GoDaddy error squared away by adding second domain name to my Hosted Domains screen, which took 24 hours to get off "pending" status. Works perfect now. Anyway...
So I wanted to go and add some links to my site(s) and then create a links page using Links Shortcode, a handy plugin for such things.
Problem is, my Links page & Link Categories are broken. On both sites, primary and secondary. As far as I can tell, other admin areas function correctly. Not sure why Links & Link Categories aren't working. (Nope, problem wasn't caused by Links Shortcode, as far as I can tell; tried deactivating it and same problem persisted).
So, the problem is thus: when I click either Links or Link Categories, no Links Shortcode (the plugin's menu option works fine), it takes me to a page that just says "Cheatin' uh?" (I'd think it should be "eh?" personally, but I won't quibble over silly utterances).
Both links point to ".../wp-admin/edit-tags.php?taxonomy=link_category"
If I instead shorten it to ".../wp-admin/edit-tags.php" Well, it does what it says and takes me to a screen for editing "tags" rather than links.
So, clearly something's pointing to the totally wrong place.
Looking through my files I'm assuming it's supposed to point to Link Manager? Wait, what?? Apparently "Links" is disabled by default post- WP 3.5 and wants you to 'install' a plugin 'Links Manager' if you want to use Links anymore? What's up with that? Silliness.
Okay, I've installed Link Manager and will test it. But that still doesn't fix the "wrong URL" on the Links button & the Link Categories menu option. Those should still get fixed.
