OpenLitespeed Wordpress 404 permalink

Hi

For the past two days I have been going over and over why my website is getting 404 error on permalinks for %postname%.

A bit of background:

Migrating a Wordpress site from Ubuntu WordPress on 18.04 to Litespeed Ubuntu WordPress on 18.04.

Main home page is working, but if I click any link with the permalink as as above I get:

“404 Not Found The resource requested could not be found on this server!” - Proudly powered by LiteSpeed Web Server

If the permalink is set back to ‘plain’, everything works.

With this in mind and from everything I have read over the last few days it is a rewrite rule issue with .htaccess. If it was apache running there is plenty of documentation about how to fix, but I have not found anything that works for Openlitespeed.

.htaccess file below

# BEGIN LSCACHE
## LITESPEED WP CACHE PLUGIN - Do not edit the contents of this block! ##
<IfModule LiteSpeed>
RewriteEngine on
CacheLookup on
RewriteRule .* - [E=Cache-Control:no-autoflush]
RewriteRule ^min/\w+\.(css|js) - [E=cache-control:no-vary]

### marker CACHE RESOURCE start ###
RewriteRule wp-content/.*/[^/]*(responsive|css|js|dynamic|loader|fonts)\.php - [E=cache-control:max-age=3600]
### marker CACHE RESOURCE end ###

### marker LOGIN COOKIE start ###
RewriteRule .? - [E="Cache-Vary:wp-postpass_c551aee75d8679e81f4ab299e8db01d5"]

RewriteRule min/(\w+)\.(css|js) wp-content/cache/$2/$1.$2 [L]
</IfModule>
### marker MINIFY end ###

# END NON_LSCACHE
# BEGIN WordPress

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

# END WordPress

#Tried adding the below into see same would apply from apache...

# BEGIN LiteSpeed
<IfModule Litespeed>
SetEnv noabort 1
AllowOverride FileInfo
DisableCgiOverride On
</IfModule>
# END LiteSpeed

<Directory /var/www/html>
 Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
</Directory>

Any help would be great, at the moment I have reverted back to old droplet until this is resolved.
