Admin side menu keeps collapsing on me

@elly12’s solution worked for me to!

Elly12 Thank You!
I’ve tried your solution, and it seems to work fine; however after further research, I believe this is the proper way to ‘repair’ the annoying auto-folding admin menu issue. It also appears that this is invoked when your browser window is less than 900px wide.

Make your browser as wide as possible, unfold the menu, go to the top-left corner of admin bar, next to W logo (right-side), [Your Site Name] / *Visit Site* (click)

This seems to write your settings to the database and makes the menu setting stick.

or you can:

Within your Database:
table: wp_usermeta
user_id: 1
meta_key: wp_user-settings
meta_value: Delete mfold=f (and leading ampersand if applicable)

This javascript check is ran within the /wp-admin/js/common.js

Well who’s brilliant idea was it to set a new meta_key in the db setting mfold=f as your new default behavior just because one time — on a whim — you decided to collapse the admin menu?

Seriously, if manipulating the database is the only means provided by which to switch it back, then this surely qualifies as a BUG. As a plugin developer, I don’t mind lifting the hood, but for the casual user who wouldn’t know the first thing about it, expecting them to massage the DB is just plain silly. Surely there’s a handle for this on the dashboard somewhere?

As one of those casual users, thank you. After upgrading to 3:5:1, I discovered the menu could collapse. Which enabled me to read all of what I was writing. But then the menu expanded. And now I want to collapse. Jetpack was the only plugin I messed with recently and that wasn’t it. I have read above comments, and although I would have no idea how to fiddle with code, I will try the user admin change trick and see if that happens. Also the screen pixels was new to me. So thanks for something that hopefully won’t be nothing.
Love,

Also a casual user here, can someone walk me through the steps to make the change that Elly12 suggested above?

I found that I could modify the WP tables in the database to unfold/un-collapse the admin menu. I modified the wp_usermeta table. I changed “wp_user-settings” from “mfold=f” to “mfold=t” and that seemed to solve the problem.

How do I access the database? How do I modify the WP tables? Can someone with Administrator access make this change? I am currently experiencing the collapsed menu with one user but not another, independent of which browsers or computers I use.

The fix Elly12 suggested isn’t working for me. The database is being changed back to “mfold=f” whenever I set it to “mfold=f” on page reload.

Same problem. I was going crazy and finally found this (recent) solution. But didn’t work.

The fix Elly12 suggested isn’t working for me. The database is being changed back to “mfold=f” whenever I set it to “mfold=f” on page reload.

The same issue.
Please help and thank you very much.

SOLVED!!!

Here the solution.

??

frankypa’s reference worked for me.

1.) Log in to phpmyadmin, click on the database.
2.) Browse the table “wp_usermeta” (if you have database prefixed, the table name is ‘usermeta’ followed by the prefix).
3.) Look for the ‘wp_user-settings’ from the column ‘meta_key’ (make sure the user_id is correct).
4.) Change the ‘meta_value’ to ‘mfold=0’, save your record, and login again.

When I refreshed my phpmyadmin after making the change, it reverted back to “mfold=f”. I made the change again and refreshed and it stuck. After that I logged out of wp-admin and logged back in and the problem was resolved.

Happened here too… after I installed an admin theme and deactivated it again.

Solved it by deleting admin user and creating another…
