Question on updating from V7.2

Copy only the common.css file from styles directory nothing else in that directory

For the cache_builders directory copy all files EXCEPT the custom subdirectoy ?

Right ?

Does this all be copied to existing functional forum directory or have to be some temp install directory on forum server ?

Thanks

Pretty much, follow the standard upgrade guide, only copy over the common.css file.

Thanks but not clear if files are copied/ overwritten to existing functional directory or make a temp install directory and run upgrade.php from there and it finds the functional directory ?

As the files are new, and are imperative to be installed; it'd be to your live forum and not a temporary location (as the upgrade guides would state)

OK got it, upgrade completed.

They should add to the upgrade document to overwrite all files to existing functional directory instead of stating to copy to a install directory so it is clearer on the upgrade process

Where do I find the new custom tag editor? I've gone through the entire admin panel but can't find it anywhere...

admin/rebuildcontent.php - second tab, although not sure why it is linked to the content rebuilder.

Found it! More questions though See http://www.ubbcentral.com/forums/ubbthreads.php/topics/211374/Custom_tags_for_tables.html#Post211374

...and if you don't have a common.css file?

It should be in your styles directory. I just double checked the zip to make sure I included it, and it definitely should be in there.
