500 Error on wp-admin after upgrade
This happened with one of our individual installs and it’s happened before (but I forgot the solution) so I’m writing it down.
After the upgrade to 4.7.1, the front of the sight still worked but attempts to get to wp-admin failed with a 500 error and the URL was redirecting to something with upgrade.php? in the URL.
Change the name of the plugin folder (I just prepend an underscore).
Revisit your login URL.
Run the database upgrade as prompted.
You should now be in the admin zone.
Fix your plugin folder name.
Easy but also easy to forget.

Enter me asking smarter people on Twitter, almost going to the forsaken land of Yahoo Pipes,I like Yahoo Pipes but one has to assume Yahoo will kill it dead very soon . . . although I’ve been hearing that for several years. and being saved by Google liking Mark more than me. So anyway, here’s the structure to get the comments for specific categories/tags. by name – http://bionicteaching.com/comments/feed/?category_name=apple by category ID – http://bionicteaching.com/comments/feed/?cat=18 by tag name – http://bionicteaching.com/comments/feed/?tag=tutorial-2 This is one of those things that barely rates a post but given I didn’t know how to do it maybe it’ll help some other wanderer and for people who want this it’ll be really useful. Thanks to Mark, Alan, and Martin for helping me out.
By default bbPress will enroll you as a form participant on every site you go to when you’re logged in on a multisite installation. It is meant to be helpful but usually results in a headache. People get nervous that people they don’t know are in their users list. Other people want to un-enroll to clean up their sites list. I found this solution a while back but since the way I did required modifying a core file it was overwritten on a recent update. It took me a while to figure out what what was done where so I’m putting it in this post as a reminder and with slightly more specific directions for other similarly clueless people. You’ll be editing the following file bbpress/inlcudes/users/capabilities.php that ought to live in your plugins directory (wp-content/plugins/bbpress) All you need to do is look for the /** Ready comment and then replace the code below with (I duplicated some code that isn’t actually replaced to help show more context)
