Although the accounts on my server generally have a lower memory limit, I've configured my Wordpress user accounts with a memory limit of 32Mb using the php.ini file and
memory_limit = 32M
Unfortunately I've found that I'm still getting the odd memory error, even on small tests blogs. I've had to increase the limit to 64Mb which in my mind seems a little high for normal usage.
What should be a reasonable upper memory limit to have on standard Wordpress installs with popular plugins? For your information some of the plugins that I suspect might be causing memory issues are:
- W3 Total Cache
- Role Scoper
