Big problems after updating to wordpress 4.6!

Also when you click on categories only the post title is showing, no text inside posts, all gone.

I think this is a problem with the theme, please look into it asap!

Is anyone else having these problems or is it just me?

My site’s gone. Just “Error establishing a database connection.” What gives?

Billy, call your host, its a connection issue. The problem I have is that all content inside posts and pages is gone, its just not showing.

After upgrading all sites do not work.
Error
PHP Fatal error: Cannot use object of type WP_Error as array in ——–/wp-includes/functions.php on line 3511

Thanks. All good now.

hi Dan14 same problem here posts are not showing after update it shows page not work ?? i dont know why it happen please any one help us?
My blog is funkation.com

Abhishek Sharma, I still have the same problem myself, I have no idea why the devs didnt test the new 4.6 update on twentyfourteen!!!

I backed up my site so Im using the old version now. Can one of the developers let us know whats going on??

i also dont know Dan18 and i have its database backup if i install new wordpresswith old version then i also work fine after chnge db name and user in wp-config.php file?
Or its possible to go back automatically to lod version?

I dont know, I did a backup before the update so I just restored it. Because you are on 4.6, can you try disabling all the plugins you have and tell me if that fixes it? If it does, turn them back on one by one and tell me which plugin caused the problem.

I’m having the same problem.

this is thread is for posts not showing after the update to 4.6. If you have other problems open your own thread.

There is a problem: My widgets have disappeared- not being shown in the admin/appearance section, hence unable to modify/change existing widgets– this has all happened since the recent (8/15/2016) update to theme Twenty-Thirteen to 2.0. Assume there is issue with the update… Tried enabling other themes but that did not work… Any suggestions?

yes, they just didnt test it!!! How do I get to contact the twentyfourteen devs?

Also here the same problem.
I had to go back to the previus version to resolve the problem.
