Blast- that makes no sense.  Definitely still have error reporting on?  And- how much php memory do you have?  Sometimes that can result in a blank page- i.e., running out of memory.

Hi Robin, scratching my head too! Error reporting is on (if I remove the cp_url variable the previous errors return). Don’t think it’s a PHP memory error, because the control panel works fine through site2.com/admin.php - and the inability to then swtich to site1.com seems related to the blank site1.com control panel…

Hm, see if you can cause queries to be shown- via adding this to the config.php

$conf['show_queries'] = "y";

Sorry Robin, not a peep in terms of showing any queries, Site 1 control panel is still blank (queries are now showing in Site 2 control panel)... thanks for keeping on it!

It’s about got to be a php error- or a memory error.  Can you up php memory to something really hight just to test- 64mb is EH setting.  I’m just- running out of other ideas.

Sorry Robin - upped php memory from 32mb to 64mb, and still no joy. My logic reckons that the inability to switch sites when logged in from site2.com/admin.php is connected to the blank control panel for site1.com… maybe if we try and fix the switching problem first?

You’re going to be fed up of me…! Anyway, don’t know if this helps, but when I login to site2.com/admin.php, the control panel login for site1.com redirects me back to the login page, rather than a blank control panel…

Hm- hold tight.  I’m going to bump this up to the crew, because it is flat puzzling me and I don’t want to run you around in circles while I make random guesses.  Which is about where I’m at right now.  Hopefully it’s something dumb I’m missing.

And- long thread- can you consolidate a couple of issues for me so I can pass to the crew:
-version and build
-any extensions you have installed

Want to be sure I’m dead solid on those two.

No problem, and thanks again! Here’s where I am now: -

- When I login to the site1.com control panel, I get a blank page
- When I login to site2.com/admin.php I get the control panel, but can’t switch to site1.com in the MSM
- Everything on the front-end of site1.com is working fine - including membership

Right, v 1.6.4 Build 20080710

Oh- I missed this:

...when I login to site2.com/admin.php, the control panel login for site1.com redirects me back to the login page, rather than a blank control panel…

That seems relevant.  Weird.  But relevant.  And thanks for the update- passing all current info to the crew.  Let’s get some fresh eyeballs on this sucker.

Any more thoughts on this one? I’ve been through all combinations of sessions and cookies etc, and still no luck…

Sorry I was slow getting back to you.  Talked to Derek about it and he suggests:
1. disable all extensions- use the big button top right on the extension manager.  Any difference?
2. If that didn’t do it- leave them disabled and let’s upload fresh files in case something got corrupted.  What I do- leave the existing folder up, upload a new, fresh copy of the system folder- bring over the config.php from the existing one- chmod cache and config.php to writable- swap out names of the folders.  That way you can easily swap back to your backup folder.

Note- if you have extra extensions, plugins, modules you’d need to copy them over as well.  But for a quick test, I wouldn’t bother.  Just see if it gets login working.  And be sure to put up fresh copies of your 3 msm files as well. 

Any luck?

Thanks Robin, a combination of re-uploading everything, and extension disabling and I’ve tracked down the culprit: -

Thanks again for your help, and generally keeping me sane!

Ah- looks like it was the automatic update on that extension that was causing the issue for you.  Glad Leevi got you squared away!  (Heh- I couldn’t fathom how that extension would jam up login- but an auto-update could do it!)

Thanks for pinpointing the problem- will likely help someone in the future.  And I’ll go ahead and put this puppy to rest.
