vb 4.2.3, couple errors in error_log

[TommyBoi]

Hi, I have upgraded from 4.2.3 beta to 4.2.3 and i noticed a couple erros in my error_log file in the forum root:

*PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 25690071 bytes) in /home/mysite/public_html/forums/includes/functions_threadedmode.php on line 23

*CSRF state token does not match one provided.

Any idea how to fix these?

First one is related to threaded mode...are you able to view threads using threaded mode without issue? If so, I'd ignore it.
The CSRF ones will turn up from time to time depending on what people are doing. Unless there's thousands of them it's not an issue.
The other two relate to the file blog.php - is this file present on the server and can you load it? If so, and these errors only appear that one time, it's probably just that didn't load on that specific occasion for some reson.

There is no blog.php on the server, is there supposed to be?
