SuiteCRM 8.3.0 Login only works after several attempts ('Error occurred while retrieving records")

I would suspect that your mod_rewrites are not configured properly yet, and you’re triggering this part of the public/.htaccess

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the start page to the front controller explicitly so that the website
        # and the generated links can still be used.
        RedirectMatch 307 ^/$ /index.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>

… although I would expect to see a 307 getting returned there :thinking:
