Thanks for getting back to me. I’m running ubuntu16.04.1. Currently I have set the memory limit to 256MB and maximum script execution time is 120s. I dont have many product attributes and about 500 orders and 200 users. I’m testing the free version of your plugin.
The woocommerce admin is now running slow even with the plugin removed. I suspect my data is corrupted.
Since it’s a copy of a production install, I’ll rebuild it from a backup and try again. It will take me some time to do this.
After more testing, I noticed my admin site is very slow with the plugin turned on. I suspect I get the error 500 either because the queries time out or run out of memory.
