UPDATE: There are now two workarounds.
Workaround One
Please note, to make this Workaround work you need to use Adblock Plus.
Until Facebook manages to solve the blank posts issue there IS a workaround you can use to make sure you still get your items with a secondary link, with some input from a member, Debbi.
PART ONE - This only needs to be done once
Step 1) Install Adblock Plus.
Step 2) Open the options by right clicking on the Adblock icon then select the "Add Your Own Filters" tab.
Step 3) include this filter EXACTLY:
facebook.com##.unclickableMask
That text has to be added exactly, especially the capital M in the middle. PLEASE NOTE: there are no gaps in the filter, it is all one "word".
PART TWO - This needs to be done for each post
Step 1) Go to post and get to the Facebook preview popup.
Step 4) If the post works fine, it's just a second link. If the post is BLANK, that link will still be clickable and get you your stuff!
Workaround Two
Step 1) Get to the Facebook window posting stage.
Step 2) Right Click and select Reload Frame.
Step 3) If it looks normal, post it. If it's blank, repeat step 1.
