Thread:Project:Support desk/Multiple importDump.php problems

I started by trying to upload a couple moderately sized files via the web interface "Import" tool. It worked fine for the small (900K) file but crashed returning a generic 500 error when trying to upload the larger (6M and 8M)files.

I did a little bit of reading and learned that for medium sized imports I should use importDump.php. From what I can tell, my files are still relatively small, but for good measure, I decided to try importDump instead. Unfortunately, I'm still having problems.

When I ran the script, I received the error:

Cannot get command line arguments, register_argc_argv is set to false

After quite a bit of beating my head against a wall, I discover that while the latest version of MediaWiki requires PHP 5.3.2 or higher, register_argc_argv has been deprecated in PHP 5.3 and removed entirely from 5.4. So, just for good measure, I temporarily downgraded to 5.2, but then I received the very uninformative response:

Status: 500 Internal Server Error Content-type: text/html

Questions:

Is there a way to get more detailed information out of my server on what is wrong, both for the importPHP and the Special Import page? What are the acceptable file sizes for imports? Where can I report the incompatibility with the the PHP versions?
