Memory exhausted error in admin panel after upgrade to 2.8

Thank you so much for your input.

I just did this one from Gestroud :
?You could also add this line to your wp-config.php

define(‘WP_MEMORY_LIMIT’, ’64M’);

This way you won’t have to constantly make the fix again whenever you upgrade WordPress.?

All errors disappeared.

Mine has been in a death spiral for a week now.
Set my WP_MEMORY_LIMIT’, ’64M then 120, then 256, 300+ a day later same issue. memory exhausted.

I disabled my plug-ins. Could it also be RSS widgets?

This is not normal. I started with 16MB Memory_Limit in the year 2006, than 24, 32 and now this is still not enough!? Really a problem on blogs, which have some more visitors.
Beside that, i got serious mysql-swapping problems due to the fact that some browser preloading all of the link rel=archive head tags. I hab to limit the mysql user with mysql limits to stop this, found several queries where explain select says “USING TEMPORARY” and “USING FILESORT” – things a good developer shoud never produce ??
I would wish for Worpress to remember his own slogan “Code is poetry”

question: Once I set my memory higher and cannot revert back to a number lower or else I get the white screen of death. How can I revert? Do I need to restart a service on the server end or something?

Yes, you have to restart your http daemon to make changes in php.ni active

OK, I got up at 4AM to try this:
Deleted /blog and re-uploaded a new set of wordpress-2.8.6 files
Restarted VPS server

Again, I had to increase: define(‘WP_MEMORY_LIMIT’, ‘333M’);
to a number higher than the previous one in order to “get to my blog” otherwise I get a blank white browser window.

No Plug-ins installed. What else can I try? It has to be something in my Database? I even tried a different template.
