vBulletin is great software, but every now and then it needs a kick in the behind to get working correctly. Occasionally, something will popup that just doesn’t make sense. Lets examine the add attachment feature.

If the “Add Attachement” button is missing from your new thread or new post page, there are a couple of things to consider:

• Is your current usergroup allowed to post attachments?
• Is the current forum allowed to post attachments?
• Is the setting: Number of attachment buttons greater than zero?
• Does the “View Permissions” for your user show that you’re allowed to post attachments?

If all of those are YES, and you are still stumped, lets dig deeper.

• Have you had a recent crash of vBulletin?
• Have you upgraded vBulletin recently?
• Do you use memcached?

If YES to any of those, or even if you had NO for all of them, lets check the cache.

Go to Attachments menu on your admincp, and then click “Allowed Filetypes.” Make sure you have some! If you don’t, that is your problem there. If you DO have some, click on any one of them. Then click “Save.”

What we are doing is rebuilding your datastore’s cache. It is an internal glob of settings that the vBulletin software uses. Go ahead and check your new post page and check to see if your Add Attachment Button is back!

Until Next Time!

P.s. Remember to sacrifice enough chickens this time so you won’t piss off vBulletin again!
