If you can get at the backoffice try to limit the number of posts from 8 to 5. For the rest this is not something you can handle with B2evo. The mySQL memory limit is apparently set at 1Mb which is not much. I advise you to contact your host and ask them if they are willing to change the settings.

Good luck

Thanks... Can you think of any reason why it just stopped working now? I've had 8 posts on the front page for quite a while, and these aren't even very long :)

EDIT:
Tried to change the limit, didn't work :(

Hey, my host fixed it! Thanks

Nice host.

Happy blogging
