Install phase explanations
PHP Fusion 9 does not require memcache. It is still in my #todo-roadmap.
Those severability detection during installation is just a gauge how well your PHPFusion CMS 9 in your server.
Local production server
I can't say for WAMP, but I recommend using XAMPP with the latest version PHP 7.1.1 (the copy that were used by our core developers building the PHPFusion 9).
3. Now to the issue:
If you can login to the admin panel, and every subsequent link gets you kicked out of admin, then it is definitely cookie issue. Test with a different browser if you are not sure whether you have cleared your cookie correctly just to oust this possibility.
However, If a single f5 refresh gets you kicked out, then $aidlink generator may be mismatching your site credentials.
Check your site path in settings and make sure your site path is the current directory path.
It will also help if you go to recovery console (install.php) and change super administrator settings with new password, admin password as a last resort. It will not harm your entry records whatsoever.
