Have you cleared all your cookies and tried to login?

delete the .htaccess file
regenerate your permalinks
admin – settings – permalinks

It will work

Sorry please delete this post.

Your wp-config.php file can be located in your wordpress installed directory. If you are unable to find it, maybe your files were deleted and you were able to see the cached version of your site.

Why don’t you download a fresh copy of wordpress and upload the new config file to your directory and try again?

Your question is too general. Hope this helps

This is what will happen if you try to delete the user.

You have specified this user for deletion:

ID #2: xxxx

What should be done with content owned by this user?

Delete all content.
Attribute all content to: (user list here)

So, choose whatever you want from the above two options.

No, before you are about to delete the user, it will ask you about whether the posts made by him can be assigned to another user.

Different themes will have it in different files. Mostly you can find it in Comments.php file or else try to search all your theme files until you find.

You need to have admin access in order to delete other user which has admin rights too.

You can delete the user by logging into your wp-admin > users > delete the user you want.

It will ask you to Attribute all content posted by the user to any other user and choose the one you want these to posts to assign and proceed to delete the user.

This can be accomplished by using Text Decoration in your css file located in your current theme directory.

Since you said, your DNS currently points to old server where you installed Joomla. So, if you try to access wordpress or its admin, you will get error but you can see the files in your directory.

You need to change your DNS to point your new server, so that you can access your wordpress.

Have you noticed?

Your non-www version of your website is not working. Try this to fix that

RewriteEngine On
RewriteCond %{HTTP_HOST} ^yourdomain.com [NC]
RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [L,R=301]

What error are you getting when you try to upload your media?

Delete your old files by keeping a backup. Upload your new files to your domain and change your db settings to point to your old content.

HTTP 500 Errors occur due to incorrectly configured rewrite rules in .htaccess. Seems like your main site’s .htaccess is overriding with your sub domains’s .htaccess file.

Did you double checked whether you have .htaccess file in your sub domain’s directory?

Probably it is what causing your problem.

It is due to the plugin cannot integrate well with the theme you are using currently. Try getting support from your theme support.
