Circular Ref Out of Mem - New kid
New kid here - new to apache, php, sql and tikiwiki - know a little Linux.
We have a new wiki site (5 days old - very small at this point). I'm getting the memory exhausted errors whenever anyone logs in. We can browse anonymously, error only occurs after login. I set the php memory limit to 16MB at install. Changed to 24MB like stated in posts here. I have even increased it to 128MB just for giggles. The apache log files state that 128MB allowed memory has been exhausted. Seems to me (uneducatedly) that there is a circular ref somewhere. The error occurred after one of the users logged in as admin and started adding articles and editors. I'm not sure what exactly he did, but he stated he added editors to the registered group and then gave editing priveleges to something and then removed the editor that was added and then it crashed. Hopefully that may make some sense to someone here, it doesn't to me.
Anyway - I don't even know where to get started debugging this, since I can't log in as admin, and I don't know php or sql enough to debug a problem. Could you please point me in right direction. How do I debug this thing. I'll settle for a simple solution at this point to get it working, but it looks like I'm going to be the admin for this, so I have lots o'learnin to do. Is there a basic theory of operation available somewhere?
Thanks in advance.
