DU2 Bug Fix

[Leopolds Ghost]

Note: this is for display purposes. DU post contains extra characters, so cutting and pasting won't work.

I can post the raw .js file if someone has a place to put it.

This script works...

Getting duboard.php to display remote links to avatars and signature lines
via userscript is just a little beyond my skill set.

1. Thanks, Leo

Nice to see you!

[Leopolds Ghost]

2. You guys need it? Or is the posting mechanism working for you?

Without the bug fix I get "an error occurred and your post did not go thru." Even though it did. So all the userscript does is redirect you back to the appropriate thread.

If any of you are having problems with that I can PM you a link to the script as a text .js file and tell you how to install it on your browser.

3. Can somebody (preferably more than one) reply and say whether the posting mechanism is working?

For you?

Or is it delivering an error when you post?

And if so do you want this patch? :think:

4. Leo, thanks for your efforts. Your skill set in this is way above mine.

I am lucky if I can type a legible post. Even if the stuff in the OP were a copy and paste, I'd still have no idea where to paste it.

For me, it is okay, though. I just backspace a couple of times after I post. I don't find that a huge deal.


I hope someone else can use your fix, though.

Whether they can or not, I am sure everyone appreciates your giving it to us.

5. Test

6. No Elephants, others -- I will post the file and give the link to anyone who requests it.

1. Go to http://pastebin.com/raw.php?i=k2dkseMN

2. Right-click on the page (or the following link) and "Save as"

du2_bug_fix.user.js

3. Under the help section of your browser, search for "user scripts". If that fails,
google how do I user scripts + the name of your browser

4. If your browser has a Preferences Panel set up to allow user scripts,
then you should be able to take the file and install it by dragging it into the panel.

5. If your browser is Firefox and you have no user scripts built-in panel,
you can install the greasemonkey plugin.

6. More information

downloaded userscripts allow you to tailor the appearance of specific websites

http://userscripts.org/about/installing

http://www.greasespot.net/

User scripts and add-ons (browser plugins) also allow you to
adblock, etc. Be careful, though: only install trusted addons.
