I really love this extension, however there seems to be a small bug.
I am using version 0.2 and I needed to uninstall this extension temporarily.
Surprisingly uninstall appeared to be impossible - due to an unhandled exception. In PunBB debug mode this error message was shown while uninstall was in progress:
An error was encountered
The error occurred on line 582 in D:\Programme\Apache\htdocs\forum\include\dblayer\sqlite.php
Database reported: SQL logic error or missing database (Errno: 1).
Note: I am using SQLite as database.
I finally figured out how to get it uninstalled manually, and meanwhile it is installed again,
but I needed to to comment the following problematic line in the uninstall section:
// $forum_db->drop_field('forums', 'last_post_subject'); //caused the error
$forum_db->drop_index('forums', 'i_last_post_subject', false);
Now uninstall works without error, well obviously uninstall is not complete - my modification was just kind of first aid. Unfortunately I don't know how to really fix this, so it would be great if you could look at it.
Sorry I can't speak Russian.
