Hey I just wanted to jump in and say that I’m having the same issue. I’m pretty sure it’s a problem with MY permalinks, but activating your plugin seems to cause the PHP error that was posted here.
As additional info: I disabled Yoast SEO and the problem went away. But today, as soon as I updated GeoDirectory’s permalink structure, it came right back.
Any ideas why your plugins would cause the problem to become worse? I have installed Permalink Manager Lite and I am rebuilding my permalinks now. I will report back whether or not that is a success.
thanks,
Kim
