Attachment selector button not showing

[IMCD]

Setting is enabled but button not appearing. XF 2.1.5

Also, "server error occured" when trying to upload attachments to this post I'm making here.

Thanks!

Sometimes you need to add the button to your toolbars in your ACP > Content > BB code button manager.
Just add the button there to your toolbars and it will appear.

Also please try the upload again, we had an internal error with uploads.

Thank you, that did the trick.
