Hello, I've a problem on my wiki. When I try to create or modify a page, it get an error 500. The strange is that it happens only in the page of namespaces User, Project, 100, 102, 104 (but not in ns0, 101, 103, 105, 150, 151). I tried to follow the page [1]: I put error_reporting( E_ALL ); ini_set( 'display_errors', 1 ); at the top of my LocalSettings.php, and it shows a problem with $wgImportSources. So I deleted it from LocalSettings, but it got the error 500 again, without further information about the error. Then I tried to increase memory limit through LocalSettings.php to 16, 32 and 64M, putting ini_set( 'memory_limit', '32M' ); but nothing changed. What could I do? Thank you in advance. Regards.
