Multisite Sub-site running DMS returns 500 Error with PL5 plugin Activated

[newportdigital+ 0]

Interesting problem discovered today. I run a multisite and have a number of sub-sites running the DIVI theme and one running DMS. Network activating PL5 plugin breaks my DMS themed sub-site, but no other sub-site on the multisite.

The DMS themed sub-site throws back a 500 server error.

I have switched on WP Debug, but no errors to report, sub-site still throws a 500 Server Error

Any help is appreciated.

 

Kind regards

Whats in the server logs?

A 500 error means PHP has had a fatal error and cannot continue, but it is always logged.

Normally by turning on WP_DEBUG WordPress enables display_errors and the fatal error is printed to your browser. If not it will always be in the server logs.
