EDIT: I will keep the running tab of reported issues and resolution items here...
Old Poll voting categories and results are lost
This is known. The upgrade process carried over the fact there was a poll, but not the option or the votes cast on each. This data is still around, and I'm working on a way to convert them over to the new table entries.
Attachments that are images show up as in-line images in posts
(FIXED) This is a feature of the new software. In an effort to be courteous of our bandwidth-challenged users, the feature has been disabled.
Spell check is bringing up a blank pop-up
(FIXED) Some dictionaries were not installed for aspell that the forum software required.
New smiley are ugly
(FIXED) I personally agree. You can change this in your forum profile:
Modify Profile -> Look and Layout Preferences -> Current Smiley Set -> classic
Will enable the old ones.
Attachments cannot be viewed and/or posted
(FIXED) The global permissions disallowed attachment posting and viewing for everybody except the Administrator role. Adjusted to allow global read of attachment, and member post of attachment.
There used to be a little light for on/offline, now it's a text thingy.
(FIXED) Yep, in fact all icons were not showing up. The Theme setting had icons to display as text by default. I re-enabled icons for all buttons, which includes "ONLINE"
Smileys are showing up as text in messages and the Message compose screen
(FIXED) Icons directory permission problem and missing files.
Attachments do not download (GIF, etc)
(FIXED) Forum was misconfigured to look at an invalid attachments directory.
Forum topic links embedded in topic threads do not redirect properly
(FIXED) Rewrite rule adjusted to not include "Escape" HTTP code '%25' when fixing ';' translation to HTTP code.
This is a known problem. It appears that our redirection system causing a translation of the ';' into it's HTTP code equivalent with an escape HTTP code: %253b. Currently, clicking the link will take you to the board index page. Substituting the HTTP code with the ';' will work temporarily.
