Where to start troubleshooting? Thanks in advance!

Can you check if the .xml file in dump/ is not empty?

Subfader (talkcontribs)

The xml created by maintenance/dumpBackup.php? Yes it is created but empty.

I have no problems running other maintenance scripts. It returns no error message at all, that drives me crazy.

Chiefgeek157 (talkcontribs)

Just saw this problem a minute ago on my own server. I had a typo in LocalSettings.php that prevented the dump from working (I personally was missing a trailing ';').

Subfader (talkcontribs)

Hmh I can check but shouldn't the whole wiki break in such case? My wiki works fine tho.

Rainman (talkcontribs)

Yes, unfortunately dumpBackup.php returns very few errors. You need to google around to make sure it works first.

When xdebug is turned on it returns this error message in php_errors.log: PHP Fatal error: Maximum function nesting level of '100' reached, aborting! in /var/www/html/w/includes/GlobalFunctions.php on line 2326 Try to turn off xdebug in php. It helped me to solve the premature end of file error when running build.

Leucosticte (talkcontribs)

Or put xdebug.max_nesting_level = 200 in your php.ini.
