php_errorlog > 2GB due to SG Security Errors

Hi,

We noticed that php_errorlog was quickly growing in size (to > 2GB), and all the errors seemed to be related to this plugin – and as soon as we Network Disabled the Plugin the errors stopped.

Below is a small extract (site, DB & IP info. removed) from the php_errorlog – every site on our WP Multisite was displaying a similar error.

Many thanks,
Nick
