3.0.4 out of memory error

You’ll need to increase the memory while doing the upgrade. It is looping through the old tables and moving everything over.

I do not have control over the memory on my web host.

I tried to set perserve settings to no then deactivated and uninstalled Plugin Organizer and tried to install 3.0.5 but still I get the memory error.

If I start from scratch does it still require the looping through the old tables and moving everything over?

I only have 2 filters set up so no problem to start over

What version are you upgrading from? Guess I should have asked that first. If you aren’t upgrading from a version before 3.0 then it isn’t moving anything over. If you only have 2 filters I’m not sure why that would cause an issue.

I was trying to upgrade from 3.0.3 to 3.0.4 and also tried to upgrade to 3.0.5 but same issue.

Ok well then it isn’t moving anything from the old tables. I have no idea why you would run out of memory.

Oh yes I do know why. It is trying to loop through your posts to see if you have any bad permalinks. You must have a large amount of posts. Try to add this to your wp-config.php file before activating it.

ini_set('memory_limit', '512M');

Just have that in there until the activation finishes.

Thanks but actually I fixed it just now by deactivating all other plugins in WP and then the upgrade worked just fine.

I released an update that should stop it from pulling all the posts when doing that check. It now uses the advanced meta query to pull all posts with the bad meta key.
