Need help in converting htaccess to Zeus rewrite.script

Help needed to convert htaccess to Zeus rewrite.script?
Themes are not working when viewing the site in subfolders, only the text is displayed

I am using manorway.org.uk as a test site for developing the new Clapham Youth Centre web site
https://cyc.manorway.org.uk/ is the main test site which will include subfolders for each area of the youth centre, eg: https://cyc.manorway.org.uk/karate https://cyc.manorway.org.uk/juniors https://cyc.manorway.org.uk/seniors etc
Clicking on one with a subfolder displays the contents but minus the theme!
I need help in getting the theme to display while using the correct rewrite.script.
All subfolders have been set to use the WP 2012 theme.
https://cyc.manorway.org.uk/ displays ok.

WordPress has provided the correct .htaccess and extra WP-config.php script within the Network Admin section that I need to use.

So, all you professional coders, can you please help convert the following (WP provided) .htaccess script into zeus rewrite.script?
I would be very grateful as this has now been bugging me for a long time.

.htaccess as produced by WP:
{\rtf1\ansi\ansicpg1252
{\fonttbl\f0\fmodern\fcharset0 Courier;}
{\colortbl;\red255\green255\blue255;\red51\green51\blue51;\red255\green255\blue255;}

\pard\pardeftab720\sl320\sa120\partightenfactor0
\f0\fs24 \cf2 \cb3 \expnd0\expndtw0\kerning0
\outl0\strokewidth0 \strokec2
# Not sure if the above script should be included?
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]}

Thank you.
