Thank you, Andre!
Below is the stack trace I got.
[d7e9d262] /xxx/index.php/Welcome MWException from line 1287 of

The versions of the new server are:
CentOS 7
Apache/2.4.51
PHP 7.4.25
mysql Ver 8.0.23
MediaWiki version 1.26.2
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
