What templates or files did you edit to fix the attachments issue? got a site link?

Repair / Optimize Tables were done. After this process the problem was solved. Then we had an another problem.

I can't give you a site link because i closed the site for users but if you want i can give to you a membership with special powers..

Database error in vBulletin 3.8.4:
Invalid SQL:
SELECT COUNT(*) AS count FROM post WHERE dateline >= 1322604000;
MySQL Error   : Table 'post' is marked as crashed and should be repaired
Error Number  : 1194

for this problem we did Repair / Optimize Tables but we could not solve the problem. I can see the older topics and contents. I can see the new topics' names but i can't see the contents.

Best regards.

Hi.

I used Prune Post Edit History. After this process it gave me an message " No Post Edit Histories Matched Your Query ". But my problem is still keeping on. ( for instance there were 19 messages which were written about the topic but when i clicked the topic, i can't see these messages. This problem is not existing in older topics. The topics which were opened in a year, this problem is existing.)

Best regards.
