Updated to 6.7.5 Pro, Cornerstone dashboard goes to 404 page

Issue: After updated to 6.7.5 , as stated, the cornerstone dashboard goes to 404 page. I was previously on 6.6.X ( don’t remember the minor version. ) I tried reinstalling the pro theme manually, disabled all plug-ins, resaved the permalinks, emptied browser cache, updated to the latest Wordpress and logged in using incognito. Issue persists. I do not use CDN or site cache as it’s a new site that’s being developed. Note - I purchased a CSAI license and installed it prior to upgrading to 6.7.5.

Also, there seems to be a plugin conflict with Yoast. When using the Cornerstone editor, global components don’t display correctly on the page unless you toggle the visibility icon (the eyeball next to the component name) on and off. Once toggled, they display properly. However, if you then save the page Ubermenu ends up with extra spacing at top and bottom. Inspector shows a skip-nav around the menu creating the space. The Ubermenu conflict goes away when Yoast is inactive. Thanks!

Hello @11Studios,

Thanks for writing to us.

I tried to update the permalink settings and access the settings page, but it appears there is an issue with the .htaccess file. This type of error is often due to problems with the .htaccess file itself or the server configuration after changing WordPress permalinks. The issue could be related to a corrupted file or incorrect file permissions. To resolve this, I recommend renaming your current .htaccess file to create a backup, then generating a new one with the default WordPress rules and setting its permissions appropriately. Afterward, please check if the problem is resolved.

For detailed guidance on creating and configuring the .htaccess file, please refer to this documentation guide.

Hope it helps
Thanks

I removed all in the htaccess but the following code. The issue remains.
Permission is set to 0644. No changes to server configuration. PHP 8.3
All plugins are currently disabled except limited login and I dumped the cache folder from the uploads.

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Edit: I’ve checked and the php extensions required for wordpress and cornerstone are installed. I just increased the php memory limit to 512MB
