Yeah all bundles products are set to allow back order but the bundle says unable to be purchased.
I fixed the bug causing the excess CPU/PHP lag in my version.
Simply wrapping the contents of load() in base_module class with a file_exists query boosts the performance by 500-1500ms in most cases in the back end and front end.
It’s a temporary solution though whilst we wait for your patched code.
I’ve fixed about 15 sites that come to a grinding halt with the plugin turned on so far.
Anything from PHP 5.4 to 7.0 all has the same problem happening even with error logging turned off and error display turned off PHP is still wasting a lot of resources dealing with the uncaught error just to not display it or log it after compiling the information.
Hope this helps you guys.
