Hello. I'm somewhat new to working with WordPress. I've only been doing it since February of this year. I'm just the developer that installs it and then troubleshoots things when they go wrong. Anyway, I started upgrading various sites to version 2.5 yesterday thinking everything was going to be just fine however it's not.
I started getting emails saying the image uploader isn't working. This is the error message the user gets when they try to upload an image...
Fatal error: Call to undefined function wp_constrain_dimensions() in /home/onscifi/public_html/stargateatlantis/wp-admin/includes/image.php on line 173
However it's not the only error message. I went into the admin panel for one of the sites. I went to the Manage -> Media Library and I see the following error message...
Fatal error: Call to undefined function wp_get_attachment_image() in /home/onscifi/public_html/stargateatlantis/wp-includes/post-template.php on line 386.
I've tried the stuff in the sticky (except for the no flash plugin) all to no avail. If anyone has any suggestions I'd really appreciate it.
