Getting 404 error message for wp-admin.php on localhost

Hello,

Rename the wp-content / plugins folder and the folder for the theme you are using to revert to the default theme. You could also check your .htaccess file in the root of your site and try restoring the WordPress default version in case there is an issue with it.

Thank you for your quick reply.

I’ve followed your instructions:

“Rename the?wp-content / plugins?folder and the folder for the theme you are using to revert to the default theme.”

But then I got a password error (I didn’t change my password).

I went to www.ads-software.com and followed the instructions for resetting passwords through phpMyAdmin.

Reset Your Password

But then this error message appeared:

Fatal error: Uncaught Error: Call to undefined function get_network() in C:\xampp\htdocs\soundsandcolors\wp-admin\admin-header.php:43 Stack trace: #0 C:\xampp\htdocs\soundsandcolors\wp-admin\index.php(137): require_once() #1 {main} thrown in?C:\xampp\htdocs\soundsandcolors\wp-admin\admin-header.php?on line?43

There has been a critical error on this website. Please check your site admin email inbox for instructions.

Where do I go from here …

In the meantime I’ve changed my theme (Divi) back to default (twentytwentyfour) following the instructions of this post

https://help.one.com/hc/en-us/articles/115005585909-Change-your-WordPress-theme-from-the-database#step-2

But after logging in I keep on getting this error message under https://localhost/soundsandcolors/wp-admin/

Fatal error: Uncaught Error: Call to undefined function get_network() in C:\xampp\htdocs\soundsandcolors\wp-admin\admin-header.php:43 Stack trace: #0 C:\xampp\htdocs\soundsandcolors\wp-admin\index.php(137): require_once() #1 {main} thrown in C:\xampp\htdocs\soundsandcolors\wp-admin\admin-header.php on line 43

Hello,

Are you restoring the core files as part of a multisite restoration?

Hello,

no it’s a simple blog site.

Hello.

I would suggest restoring it on a new local WordPress instance, there could be some missing or corrupt core files.

Hello,

I did it. First installed WordPress from www.ads-software.com to get a basic WP site.

Then used the restore function from Updraft Plus (dowloading the six back up files from my Google Drive to my desktop and uploading all of them to my localhost site.

From the outside everything looks nice and works, but still I can’t enter my new “house” (WP dashboard). And that’s frustrating.

I’ve fixed it. In phpmyadmin I deleted the password value in the ‘user_pass’ field and replaced it basically with the same password.

BUT under the ‘Function’ column, I selected ‘MD5’ from the drop-down menu and then it worked.

I’m not a developper, but maybe it was just that the MD5 setting was not correct, IDK.

Now, I can enjoy my blog again from the outside AND inside.

Thank you for your assistance on this matter.

CORRECTION:

It was the SiteGround security plugin causing the issue. I forgot that I deactivated the security plugins while trying to fix the problem. After reactivating SGS the issue reappeared.
