Error 403 and htaccess

Here’s how I’ve always seen that done:
RewriteRule ^greyhound/(.*)$ /$1 [R=301,NC,L]

It basically just strips the string greyhoud out of it so if someone typed in https://www.greyhoundwiki.org/greyhound/index.html
it would take them to https://www.greyhoundwiki.org/index.html

My mistake. That first line is one old rewrite rule. It must be ther cos out there is some links.

Problem is that:

WP is in the root (https://scooped.org)
I have a subdomain (https://galleria.scooped.org) and that is actually only one directory, /root/gallery
Now that URL gives 403 error because of .htaccess by WP installation.

I must put somekind of rewrite rule in the htaccess but no idea what.

I realize that this is likely too late to help you, but for all those people that end up here, as I did, looking for an answer…

If you install wordpress in your server root, and suddenly files that are in already-existing directories are returning 403 errors, go into that subdirectory, create an .htaccess file and type this in it:

RewriteEngine off

For example, my domain had an images folder in the subdomain. I installed WP and all the images from that directory were forbidden. I stuck an .htaccess file in the “images” directory, and then life was golden.
