All my posts go uncategorized!

Everything okay in your WP-Admin?

Settings >> Writing >> Default Post Category
Settings >> Permalinks

permalink seems ok but
Settings >> Writing >> Default Post Category shows a small checkbox , like halved, shows nothing, no yes, no true/false, no options at all,

Screenshots see here fro permalink https://www.wedmepretty.com/?attachment_id=1889
see here for default category : https://www.wedmepretty.com/?attachment_id=1888

Posts >> Categories

Are they all there? Do you have some sort of conflicting SEO plugin that alters the categories?

If you’re familiar with databases, perhaps use phpmyadmin to check out what’s going on? https://www.wpbeginner.com/beginners-guide/beginners-guide-to-wordpress-database-management-with-phpmyadmin/

Yes the categories are all there I did not install any new plugin
I try to go to php my admin but it gives me this error
“phpMyAdmin – Error

Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.”

I also get this error when I try to update a plugin, maybe both issues are connected?

“Downloading update from https://downloads.www.ads-software.com/plugin/akismet.2.5.9.zip…

if I install a fresh copy of wordpress, the what do I have to do to get back all my posts and categories? which folder do I need to replace from the backup?
