Server Timeout due to WP MU DEV

Hi Support,

Server Timeout Errors

When we are running a WP import we are running into period server termination errors. These errors seem to be caused by WP MU DEV plugin (according to our server error log, please see it here: http://bit.ly/2kThwWh). This is strange as we are currently not running 'Smush' (although the plugin is active).

Please can someone help us resolve this (if you need to login to our WP site and don't have the login details, please let us know and we will reply with them).

Thanks
