Same issue here! QSM plugin suddenly caused a critical error on my site yesterday. Tried everything – updating, rolling back, switching to Twenty Twenty theme, disabling all other plugins – no luck.
On a side note, dealing with tech issues makes me appreciate simple systems like the Emirates ID status check – no complications, just quick results from the UAE government site. Wish plugin troubleshooting was this easy!
Any solutions yet? My site’s still down and I’m getting desperate!
