After I made a WordPress 2.5 Interface Review I decided to upgrade my blog and to test “on live” the new improvements & features. The upgrade process went fine, I have no problems. I must admit that the new WP 2.5 is great, a lot of improvements but I still don’t like their color scheme.

If you don’t know how to upgrade you blog read the Upgrading instructions or contact me and I will help you.

But!!!! Writing the previous post I found one big problem or bug. I do not know exactly in my case if this was a bug. I could not upload images to the post, and I wasn’t very happy about this. After a long research I found a list of solutions to the problem, Things to try. In my case the #7 worked, it was the only one that I tried because the other I excluded:

1. Make sure you uploaded all the WordPress files correctly. Really, this is probably the most common upgrade problem.

2. Clear your browser cache, restart your browser. Do it twice. Browser caches can be persistent little things.

3. Update your Adobe Flash to the latest version (esp you Linux users!): Flash

4. IE has specific known issues. Download these two files, replace them in your WordPress installation: IE-Fix

5. Another known issue is where the media buttons don’t appear at all. This happens when you have an older plugin interfering with the JavaScript. I encountered this problem with an older version of WP-Amazon, but any plugin loading its own jQuery can cause the issue. Disable your plugins and see if the buttons appear. If so, reactivate one by one until they don’t appear any more. Upgrade all your plugins as well.

6. Bad Behavior breaks the uploader. Disable it. There have been reports that editing the “blacklist.inc.php” file to remove the line containing “Shockwave Flash” also works.

7. mod_security might be causing problems. Disable it to see if that is the problem. To do this, make an .htaccess file in your wp-admin directory. Add this to it:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

That will disable it for the entire wp-admin directory. It’s possible to be more specific about it, this is just a quick and easy test to see if mod_security is causing your issues.

8. Worst case… Disable the flash uploader for now, using this plugin: No-Flash-Uploader

But most importantly, stay tuned. If any new developments or fixes come to light, we’ll update this post. For now, not all problems can be solved. Patience.
