Internal Server Error 500 doesn’t really tell you what is going wrong. You should check your server logs to find out what the real error is.
Sorry, I am not familiar with this work. Now I have the log, what must I search?
There should be an error in your log that occured at the same time you got the Internal 500 error. The error in your log should point you at what the real problem is. If you don’t know when you got the error; try to recreate it and then check your server log to see what it says.
I can get the log files from my provider Strato with some delay. Today I can get the file from December 13th. The only 500-hints are linke this:
217.82.248.80 – – [13/Dec/2004:19:29:31 +0100] “GET /journal/index.php HTTP/1.1” 500 540 “-” “Mozilla/5.0 (Macintosh; U; PPC Mac OS X; de-de) AppleWebKit/85.7 (KHTML, like Gecko) Safari/85.5”
66.196.91.53 – – [13/Dec/2004:21:57:15 +0100] “GET /journal/index.php?m=20040621 HTTP/1.0” 500 528 “-” “Mozilla/5.0 (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp)”
Is this helpful?
Now the mistake didn’t occure for a longer time. I checked often the weblogs.com.changes.cache. When it reached nearly 500 kb I deleted the most part of it, so it was only 5 kb – and then it worked for another period.
Then I finally checcked the index-Page again and I saw:
// Uncomment the next line if you want to track blog updates from weblogs.com
include_once(ABSPATH.WPINC.’/links-update-xml.php’);
I uncommented it and since then there was no server error 500 again. I don’t understand exactly what happens with the connection to weblogs.com. Bit now its ok
