uh oh, same here i think.
Not the exact same as @mj but .. i had a working site, and now i have missing content on the front end. the data is still in the database, but i cannot get it to appear on the front end. Some of it is there, some is ignored (or something) .. going to try ‘rolling back’, not exactly sure how but
/ edit /
Rolled back to Version 5.0.8 and it’s all working again.
That was a nightmare.
