    Hello @hlinte3

    Hope all is well!

    Locate the .htaccess file in the site’s directory, keep a copy on your local device just in case and remove it from the site.

    From the network admin, go to Settings > Permalinks and re-save the changes. Check if this fixes 404 errors. After this, the .htaccess file will be regenerated again.

    Hope this helps!

    Cheers,
    Nastia

    Hi,
    I also think the problem can be in the .htaccess file. If it’s generated automatically by WordPress and you haven’t edited it, that may be the problem.
    Here is how it should looks like:

    # BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
	# WP Maximum Execution Time Exceeded
	<IfModule mod_php5.c>
	
    php_value upload_max_filesize 1024M
	php_value post_max_size 2048M
	php_value max_input_time 3000

	php_value max_execution_time 3000

	</IfModule>

    It can also be a plugin. The most common plugin to do such errors is the “Slider Revolution” plugin. If you have it too, simply deactivate it and check if the website works in the correct way.

    Hope that will help!

    Hello @hlinte3

    Hope all is well!

    As atanas1223 mentioned, please try adding the default define rules into .htaccess. See the sources from here:
    https://codex.wordpress.org/htaccess

    For single WordPress site

    # BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

    For Multisite subfolder

    RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

    If you still experience the issue, choose the option ‘Default’ in Permalinks page then save changes.

    Go to Settings > General and check the WordPress address (URL) and Blog address (URL) set correctly (no slash at the end of the URLs).

    Hope this helps!

    Cheers,
    Nastia
