Tried installing on a WP server. Versions: WordPress version 6.0.3 Active theme: Twenty Twenty-One (version 1.6) Current plugin: CiviCRM (version 4.6) PHP version 7.4.32 Zend Engine v3.4.0, Zend OPcache v7.4.32 (what's a Zend..?)
Installation location is /home//crm/wp-content/plugins; I don't have root access: this is a shared server, but I do have proper bash access as a user via cPanel terminal. Installation crashes at the point I go to wp-admin settings and click on "civiCRM installer".
The diagnostics are "There has been a critical error on this website. Please check your site admin email inbox for instructions." and An error of type E_PARSE was caused in line 1 of the file /home//crm/wp-content/plugins/civicrm/civicrm/packages/DB/DataObject.php(207) : eval()'d code. Error message: syntax error, unexpected 'clone' (T_CLONE), expecting '('
This looks similar to Installation on local wordpress server but using much more recent versions.
In that trouble ticket the user did some digging into what the database itself was doing. I don't have that knowledge.
