Cannot move widget to the sidebar

I have to add:

I can also not use the menu “Screen options” or “Help” on the widget page or any other page.

When I compare the two installations, I can see that in the new one (which does not work), as I click on the Screen options menu up on left corner in the widget page, the following comes up in my browsers url address line:
https://fjeldvig.no/GenblogEN/wp-admin/widgets.php#screen-options
When I do the same in the WordPress I upgraded, and which works, only this comes up when I press the menu:
https://blogg.fjeldvig.no/wp-admin/widgets.php (no #screen-option)

The same happens when I press the “help” button #contextual-help is added.

I have no plugins activated, and use the WordPress Team that came as standard.

Delete the wp-admin and wp-includes folder. Upload new folders to the server.

That was a very bad idea.

By deleting the folders and uploading fresh ones from the server, everything got messed up. Fortunately i had a backup, so I could restore again.

If I should upload the folders again, I guess a few things must be modified, and i am not a technical person to do so, without some guidance..

If this was a serious attempt to help, please provide some further instructions.

what version wordpress are you using.replacing folders should not have caused any problems

Deleting and replacing wp-admin and wp-content should do nothing to mess up wp and is one of the standard, normal trouble shooting techniques. Only if you deleted your wp-content and or config.php would you have a problem and I did not tell you to delete those.

All my responsed are “serious attempts” to help otherwise I wouldn’t be spending time here.

I am not insinuating your answer was not serious, just that the instructions were not accurate enough, and that I probably needed more help if I should make it work.

When i said things got messed up, this is just what happened. I could not open the Home page, only some errors showed up. I should probably have copied them.

After deleting the wp-admin and wp-content and replaced with new folders without any luck, I replaced them once again with the same folders from an other WordPress blog I have and which works fine. This also caused a mess, with error messages.
So finally I deleted also this ones and restored the ones I had before I followed the first advice here to delete and upload.

Strangely enough, after copying back my original folders the second time, the widgets and the menus worked!

So, after all, it all worked out. Thanks!

Good. Copying back the folders corrected something that went wrong in the initial deployment.

Glad it worked out. Please mark resolved.

HEllo

I have a similar problem with the latest two versions of WordPress.

Trying to clear up how to do the erasing.

I assume I can look up with a host filemanager the two folders you suggest and delete them.

Now this is where it gets confusing.

How do you upload the folders again when they are gone?

Do I create two new folders in the same position they were before?

I am using a hosted version of WP at bluehost.com.

Thanks a lot.
Happy New Year!
