[ask] How to Optimize vBulletin

Resolved. Its my hosting problem.

Edit : More question :
I got this error all the time "500 Internal Server Error".

Here's my cpanel error log

Code:

...(truncated)...

Anyone knows what's wrong with my vbull, i suspect the "Premature end of script headers:" message, but have no idea. :confused:

have you edited showthread.php at all? The logs do not really help any on diagnosing the problem.

"Premature end of script headers" errors appear with vBulletin frequently when the doc_root in php.ini does not match the DocumentRoot in httpd.conf. Make sure those are the same.

If the paths are identical, here's Apache's Docs on "premature end of script headers" errors.

No, i have not modified any core vbulletin file. I also have disabled all plugins to check if some of them causes the error & performed diagnostic check just in case some of my files are corrupted. But i still get the error.

Here is more log

Closing, as requested.
