Altough i'd feel better if the code or mysql was fixed instead of hiding the errors. Does this not consume unnecessary performance? Since the code in it calls upon empty or non existing tables?

Updated code to fix a bug in the login for 0.1.11.

How do I make the posts visible by default? I keep having to click the text at the bottom right to make the images appear. Or is there a hidden setting somewhere?

EDIT: Fixed it by commenting the following:
//<![CDATA[
filterPosts(posts)
//]]>
in post_list.php

Now there's this issue where some thumbnail will not load (or generate?) after running thumbs_fix.php.

EDIT2: webm don't want to load, heh...

0.1.x does not support WebM.

how to put ads?

You'll have to get the ad code from your ad provider, and paste it into the Gelbooru source where you want the ad to show.

Any news ? This release is like 14yrs old now, could be cool to have some kind of news, there is no sign of a public 0.2 too...

0.2.x won't be public.

There is no work being done on 0.1.x unless someone finds a critical bug that makes it unusable. All work is being done on either the 0.2.x branch to add features to the live site, or to 0.3.x which will replace both 0.2.x and 0.1.x and will be released open-source. We're prioritizong 0.2.x right now.

when will 0.3 release?

When it does.
