Hello. The latest version of mediawiki is installed on my website. (on ubuntu 18.04, php 7.2)
I exported some pages on my site (.xml).
then when I give this command in ssh interface I get the following error.
php importDump.php --conf ../LocalSettings.php --uploads ../Vikipedi-20191123083406.xml
```
PHP Warning: call_user_func() expects parameter 1 to be a valid callback, cannot access private method BackupReader::reportPage() in WikiImporter.php on line 474
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, cannot access private method BackupReader::handleRevision() in WikiImporter.php on line 500
Done!
You might want to run rebuildrecentchanges.php to regenerate RecentChanges,
and initSiteStats.php to update page and revision counts
```
Thank you in advance for your help.
