Hi Everyone. I ran into this same issue on my wife’s site after the most recent updates of WordPress & Jetpack. I received 500 errors when trying to publish a post, when trying to delete a post received a message saying trash error. Though both worked! Also 500 errors when commenting on a post. When I tried deactivating all plugins Jetpack was the only one that did not work and gave a 500 error. When trying to delete or disconnect from WordPress I also received 500 errors.I also lost my widgets page. I have since deleted Jetpack plugin through FTP and everything is back except when people try to comment on a post it still gives 500 errors??? Even though Jetpack has been deleted. Have been dealing with this problem for a week, unfortunately I am not a code genius & support was closed. I LOVE Jetpack and am hoping someone has a solution fast.
