I can no longer "reindex questions and answers". The other functions on the statistics page work, except for this.

What happened, and how can I fix this?


Thanks for your help.

Please switch off JavaScript in your browser, then click the reindex button again. A more detailed error should then be shown in red in your browser window, and you can send it to me or edit your question here.

I figured it out, apparently you are not supposed to delete the installation file?

I'll check into that. If so, I need to change the advanced instructions or qa-install.php file so that you can still reindex stuff without it.

Thanks. I re-uploaded, but it is STILL broken now unfortunately. I really need to get this working soon.

Here is the latest error, from when I re-uploaded the install file:

===================================================


I have done a multi-file diff on my qa-includes, there are no changes which could affect this. Something has messed up the database itself or so it seems, can you help me fix my database? I have not done any edits to it via phpmyadmin, so I am in the dark as to why this happened.

I'm not exactly sure why this is happening, but I think you can fix it by inserting:

if (!empty($wordtoid[$word]))

at line 108 of qa-app-post-create.php, between:

foreach ($contentcount as $word => $count)

... and ...

$contentwordidcounts[$wordtoid[$word]]=$count;

Awesome, it worked!
