Hi, I just updated from 1.6.8 to 1.7.1 and everything seemd to work. But when I save a page/ article, I sometimes get the following error: "REPLACE INTO 'searchindex' (si_page,si_title,si_text) VALUES ('2815','sudan',' text bla blubb') in function "SearchMySQL4::update" error:"1062: Duplicate entry ' ' for key 3 (localhost)" When I updated I immediately got the error that something is not right with table "searchindex" and I have to repair it. I repaired it with "REPAIR TABLE searchindex". After that I got the error mentioned at the beginning. When I analyze the table ("CHECK TABLE searchindex") I get the following messages: "table: wiki.searchindex ; op: check ; msg_type: error ; msg_text: key in wrong position at page 50176 table: wiki.searchindex ; op: check ; msg_type: error ; msg_text: corrupt" If I repair table again, I get the error again next time I analyze the table. What can I do about this? If you need further information, I can send it. version: mediawiki 1.7.1 php: 5.1.4 mySQL: 5.0.20-max-log Thanks so far, Dars
