Upgraded a 2.5.1 WP to 2.6 and ran into the “Insert Image Into Post” problem that I’ve been seeing on the forums. I ran into the “Uploading Image” problem upgrading from something like 2.1 to 2.5.1. I did the suggested actions from Otto42’s “Image/Media Uploader problems” in the support forums, and it worked on the upgrade TO 2.5.1, but didn’t help with the 2.6 upgrade. Prior to the upgrade, there was no problem inserting images into posts using IE 7, Safari, or Firefox.
On the 2.6 upgrade, I was having problems at the point I hit the button on “Insert Into Post” from the media library. The post editing area didn’t show anything, but when I previewed the post, the picture was there. I’m helping an amateur blogger who does not have a big expertise on WP (neither do I, but have a strong computer background) so I downgraded the WP files back to 2.5.1 off my backups but forgot to downgrade the database back to the 2.5.1 backup time. Still had the Insert Image issue in 2.5.1, but then I remembered that I needed to downgrade the database, so I restored it and the Insert Image problem disappeared.
… well… almost…
There are no issues with IE, but Safari and Firefox still have the Insert Image issue and show a blank editor, but the picture comes up when the post is previewed. No problems with IE 7; uploading, inserting image, resizing the image and posting have absolutely no issues.
I’m guessing that this may be a database setting issue at this point? Any reason why IE works but Safari and Firefox don’t anymore?
