Fatal error: Allowed memory size of 536870912 bytes exhausted

I added
define(‘WP_MEMORY_LIMIT’, ‘512M’);

to the config file but no effect…

I appreciate that the last warning is from the DM plugin but it’s not DM that’s triggering the memory error. Your install is exhausting 512M of RAM.

If you had no active plugins (except DM) & one of the Twenty* themes your site would run fine in 64M.

How can I fix this issue?
Same problem here … also with all other plugins deactivated.

Error occurs only when trying to update the multisite at “../wp-admin/network/plugins.php” everything else runs smooth.

@diesignatur – Are you saying your install exhausts 512MB of RAM when you attempt to update the network?

Maybe something is misconfigured I dont know. I can increase up to 1024M and the errors still occur.

@wpmuguru: is there any way to contact you private to give you access so you can see the errors by yourself?

I would suggest the following

– reinstall the current version of WordPress. It doesn’t happen often but sometimes files are missed during the install.
– rename both the mu-plugins & plugins folder to ensure that nothing is running on the main site while attempting an update
– try the update then rename mu-plugins & plugins folders back to their correct names.

I reinstalled with a fresh version of wordpress 4.8.

When disabling the domain mapping plugin and changing the sunrise.php to the “stock file”, no error appears but of course domain mapping is out of order.

What I can say now is that the domain mapping plugin seems to be responsible for the error.

This is the current error output:

All I’ve changed before the error appeared was the “DOMAIN_CURRENT_SITE” in wp-config.php for my admin multisite (not visible for public) as the domainname changed. Of course I changed all the old url information in the database as well, so that I dont see any problem with that.

Do you have any ideas what I can do?

“stock file”

WordPress does not include a sunrise.php.

All I’ve changed before the error appeared was the “DOMAIN_CURRENT_SITE” in wp-config.php for my admin multisite (not visible for public) as the domainname changed.

If you changed the URL of your main site by editing the database then likely you have created an incompatibility that only presents itself with mapped domains.

With stock file I mean the sunrise.php from your plugin zip folder.

How can I solve this incompatibility? I have changed ALL tables with the old domain.
