Updated multisite to 3.1 and now my plugin page is blank

Are all your plugins network activated? IF so, they are under network admin plugin menu.

It’s a plugin issue – deleted all my plugins and the page is back. I’ll readd them one at a time to find the culprit.

Hi folks,
second attempt at typing this! Bah!
I read Mamaestes post with interest because we have had similar issues. We’ve been running a WPMU setup for several years and upgraded it directly to WP3.0 and WP3.1.

We noticed after a while (mainly because we don’t touch the ‘top level’ blog much) that the platform isn’t behaving correctly where the main blog is concerned.

Two things,

a) like mamaestes (but perhaps not the same) our plugins page for the first blog doesn’t load when you hit the ‘plugins’ link in the LSH nav menu. Instead you get the ‘edit plugin’ page for whatever the first activated plugin happens to be.

b) Menus disappears completely from the LHS Nav.

For all other blogs hosted – these are present and correctly direct you to
/plugins.php and /menu.php respectively. We can still put these in by hand on the first blog- but its a bit of a pain, and worse – some plugins just don’t work correctly

Happily (kind of…) one of the plugins helped shed some light I believe, in as much as it complained about blog ID 1. AFAIK in WPMU the prima blog had ID0, so I’m going to make a leap and say perhaps its still ID0 post-upgrade -= instead of the newer idea of your prime network blog being ID1 under WP3.x

Would that be likely Andrea?
If so – the only thing we can think to do Andrea is either
a) carry on limping or
b) create a brand new install and manually export and import the content (and all the plugins, people and so on *groan*) in the hope that the new copy would employ expected Blog ID’s.

Or… well, once again Flabber=Gasted, so any light you might shed much appreciated.

No. the main blog in WPMU *always* had an ID of 1. It;s only in multisite, 3.0 and later, where it does not, and *only* if you enabled the network since then.

Before doing anything, I woudl deactivate all your plugins. And you know I mean all of them, not just ones you think might be it, or the ones you just can’t live without… All of ’em.

A better stab in the dark guess is you have some old plugins in /mu-plugins/ that haven;t been upgraded in ages. those ones don’t do callbacks, so you really need to go check them and upgrade them accordingly.

And read your error logs. really, this is a teeny niggling issue in the grand scheme of things, and redoing the whole lot is kinda the nuclear option.
