Dear all,
I am restoring my mediawiki website on a new server. It happened this error: [4027854c] /dir/index.php/Welcome_to_MyWebsite MWException from line 1287 of /var/www/xxx/dir/includes/parser/Preprocessor_DOM.php: PPFrame_DOM::expand: Invalid parameter type
Do you have any ideas? What does it indicate? I look forward to any help. Thank you all!
Best, Catherine

Please see https://www.mediawiki.org/wiki/Manual:How_to_debug to get a stacktrace and provide MediaWiki and PHP version information for both servers.
Thanks, andre
Thank you, Andre! Below is the stack trace I got.

As I am restoring from my backup files and the old server was down, I don't have the information about the old server.
Please let me know if more information is needed! Thank you and look forward to any further help!
Best, Catherine

How are you doing the backup/restore? did you backup your database and re-download mediawiki? are the versions of PHP the same on both servers?

You seem to combine a recent PHP version with an old, insecure, and unmaintained MediaWiki version: https://www.mediawiki.org/wiki/Compatibility Please upgrade for your own safety: https://www.mediawiki.org/wiki/Manual:Upgrading
Thanks, andre
Hi John, I backed up my database and the entire wiki folder. I didn't re-download MediaWiki this time. I directly loaded the backup database into the new server, and moved the entire wiki folder. I don't think the PHP versions on both servers are exactly the same. PHP on the new server is 7.4 while on the old one maybe 7.0 or similar. Thanks! Catherine

I used the following commands to backup and restore: mysqldump -h localhost -u user -p --default-character-set=binary database > database.sql mysql -u user -p -h localhost database < database.sql
Thanks!
