Unable to upgrade zencart because wordpress is not

Okay,

I have a wordpress system https://example.com, everything works fine. Basically I also have zen cart installed in the system. https://example.com/shopcart/ is the url for zen cart.

I am trying to upgrade zencart to the latest version. For which, I have backed up the files and database. I have uploaded the latest version zencart files to https://example.com/test/ and when I try to load https://example.com/test/zc_install/ I am redirected to a 404 page.

The <title></title> of the 404 page says 'Nothing found for Test Zc_Install'. I am sure wordpress is looking for an article by this name. I have tried many solutions, but it is not working.

Below is my .htaccess:

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

The system uses permalinks. The permalink is set to custom structure: http://example.com/%post_id%/%postname%/

I know that wordpress loads the root index.php file first and prepares the query. Is it possible to temporarily stop wordpress behaviours and allow me to access the URL https://example.com/test/zc_install/ ?

Any help would be extremely appreciated. Thank You.

The WordPress apache rewrite is catching all of your requests when they come into the website root directory.

You could add the following to the top of your Rewrite Rules:

RewriteEngine On
RewriteBase /
# add this line to ignore all re-writes within the TEST folder.
RewriteRule ^test - [L,NC]

This will ignore all requests which contain the test/ directory. I would then suggest that you add a separate .htaccess file within your Zen base folder to handle any smart SEO mods etc from there, rather than cluttering your main .htaccess file if possible.
