The connection from MainWP to its child plugin fails if the target site uses the plugin “SQLite Database Integration” SQLite Database Integration – WordPress plugin | WordPress.org
MainWP reports already existing public keys, but this is not true, because the PHP error message of the child plugin says the following:
2024/08/29 11:38:03 [error] 768687#768687: *5144149 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function mysql_query() in /var/www/web/wp-content/plugins/mainwp-child/class/class-mainwp-child-db.php:55

I’m not sure if this is a bug, because MainWP may not adhere to the standard of WordPress itself or simply the support, for the future SQLite support of the WordPress core is still missing.
In any case, MainWP is the only plugin that seems to have problems with “SQLite Database Integration”. In the forum, the knowledge base and via Google and Bing, I could not find any further information on this.
Is there a way to configure MainWP Child so that it adheres to the standard database queries of WordPress or does an update for the MainWP plugin have to be released first?
Many thanks in advance.
