Hi, I have the same issue using 1.2.8. I also tested with 0.9.3 before the update, and the error is already in this version.
This is due to the LEFT() method in the frontend/class-custom-permalinks-frontend.php, lines 64 and 75.
My setup is:
– I have a page [my-domain]/parent-page/something
– …and have created a custom permalink, so this page has the URL [my-domain]/something
– the result is, that [my-domain]/something/sdgfagf32urg32jb is also accessible, uses the theme’s index.php template and shows a list of posts with pagination
Are you already fixing this? I could have a look into the code as well.
Why ist the LEFT() function there anyway?
