Yes – I see this now also. The problem it seems is your logs are being saved and the permalink is the same for a published post. This is where the conflict is.
Unfortunately, there are no options in the “Custom Permalinks” plugin to have it ignore the post type “wpgsi_log” and I’m not a developer so I can’t mod the plugin to ignore the post type.
Perhaps if you added a feature to disable logging, that might be a workaround?
I don’t know how many sites are using both plugins at the same time so perhaps this is a unique issue. Unfortunately, it’s not unique for me. ??
Any other way to either log the info somewhere else/another way or, disable logging?
