"jQuery is not defined" error when moving Wordpress installation

Question

I've been searching all over Stackoverflow about this issue but none of the solutions seem to work. I migrated an existing wordpress installation (database + files, same domain) to to another hosting. These are the errors i'm getting, all jquery related: Uncaught SyntaxError:

Invalid or unexpected token
Uncaught ReferenceError: jQuery is not defined

screenshot of errors in wp-admin

I tried to add "define('CONCATENATE_SCRIPTS', false);" to wp-config.php and add Jquery script tags directly to theme's header.php file

Can you please guide me with this problem?

Something is clearly wrong with your jquery.js (and probably not only that). it looks to me like some weird error with the charset of the filesystem. or a corrupted file/transfer, like zipkundan mentioned. But you said you replaced the files.

i copied the code of your jquery.js directly into the console. same error like you get.

then i copy the code of one of my installations (same jquery version) the same way, and it works.

Take a look at the screenshot, on the left is mine, on the right is yours. This MIGHT also be a problem when unzipping the installation or transferred files. try to upload the individual files via FTP.
