You need to restart apache after this to make sure your setting are updated.

I have the same problem on Mautic 4, no clue what causes it. Even upping my memory requirements to crazy amounts (\>1GB) doesn’t help

I get around this by opening the index\_dev.php file instead of the index.php, since it clears cache for you. For me, that looks like localhost/mautic/index\_dev.php. I believe using something like `symfony serve` in the command line achieves the same effect, but not 100% sure

Hi,

when I was encounter the issue in different setting, it was due to loading heavy objects into memory. I did not encounter this during the cache clear.

There were cases were cache:clear is not effective, because of this (and the error above) as workaround I would suggest clearing cache like this from Mautic root dir:

```auto
rm -rf var/cache/dev/* var/cache/prod/*

```

I suspect something, could @bradycargle run this command:

```auto
php bin/console mautic:plugins:reload --env=prod

```

and let us know if mempry error still appears? Thanks.

As far as I know running dev mode disables most cache but not all (for example Config/config.php files). So one way or the other you have to clear the cache at some point.
