A few month ago I wrote a blog post about the Wordpress 2.7 image upload problem. At that time like hundreds of other wordpress users I could not get images to upload to my blog properly.
It seems to me however that there are two separate problems, and people aren’t clarifying which of the two they have.
#1 The upload feature starts properly, but the images don’t upload correctly. This issue seems to have been dealt with extensively here and appears to be a permissions / caching issue.

#2 The uploader is meant to open in an ajax layer like the following image, but instead moves to a new browser window so the upload can not be inserted into a post. Because the “insert into post” button goes to a white screen it looks like things haven’t uploaded, leading to more confusion.
At the time, I made this video to demonstrate that I had found the culprit on our system was the comment luv plugin. As you can see, I can show it having an effect, but couldn’t explain why and suggested it was probably just conflicting with another plugin.

Anyway, I felt bad as I liked the plugin but couldn’t use it, and really just wanted to demonstrate to the wordpress community incase this gave someone a new lead towards a solution, and I didn’t have time to trouble shoot the problem further. All has worked great for a number of months and now suddenly after the last Wordpress update the image up-loader stops working again despite not having the plugin installed any more.
So today I find that a plugin called “Google Positioner WordPress plugin” is the culprit. I deactivate and the image up-loader works, reactivate the plugin and the up-loader dies.
I don’t know why, but this time I wonder if I can guess the answer. That is that wordpress 2.7 relises very heavily on jquery and this plugin does too. Unfortunately instead of using the wordpress script the plugin installs it’s own older version. Could it be that these are conflicting with each other causing the issue?
When I started to look at Wordpress themes and plugins I was shocked how many distributed there own copies of the script and were out of date.
That doesn’t however explain the Comment Luv plugin as that doesn’t seem to use jquery at all.
Oh well, again, I am just sharing hoping it gives someone a clue. And again my humblest apologies to the plugin authors, these are two great plugins and I am not trying to be disparaging.
All the best.
