I’ve just had to fix the convert_smilies function in b2functions.php in order to maintain XHTML compliance.
Diffs are:

diff -r1.2 -r1.3
205c205
< $content = str_replace($smiley, "<img src='$smilies_directory/$img' />", $content);
---
> $content = str_replace($smiley, "<img src='$smilies_directory/$img' alt='' />", $content);

I’ve added an empty ALT attribute to the IMG tag.

I’ve incorporated Dodo’s hack plus my hack of that hack into the 0.6pre3 version of b2archives.php. Note the sort by title/category does not use the proper date formatting stuff. I’ll get around to that shortly. You can get the file here

OK. Sorted out the new version. It’s now running live on this site. I had just one more problem (after I’d got the tar file extracted) which must be a PHP version difference between my local machine and my hosts server. A set of variables were out of scope causing a database access to fail on the stand alone archives page. Sorted now. I’ll look at the calendar next.

I managed to merge the new version with the various hacks and my own tweaks (good old CVS). It seems to work OK.
Unfortunately, for ease of use, I had ftp-ed my whole repository onto my local machine, did the merge there, committed my changes, tar-gzipped it back up with cygwin‘s tar and ftp-ed it back to my server. At which point it refused to untar as the UID and GID values are different from those on my server. As I don’t have root on my server :-), I don’t know what to do about it. I could ftp each file individually, but I really don’t want to do that if I can avoid it.

I’ve managed to address Sansom’s problem with the archives page, or at least I think I have. You can get the updated version. Sansom, let me know if this addresses the problem you found.

I noticed that a new version of B2 has been released. I’ve just downloaded it, I’ll try it on my local machine and attempt to merge it with the various hacks I’ve installed along with my own tweaks.
More when I’ve got it.
