I’m having similar issues, only slightly different. Whenever I attempt to generate a thumbnail (either on upload or manage gallery), it appears to go through the process with each progress indicator bar going to 100%, only to be replaced with an error message (object: XMLHttpRequest).
I’ve tried both IE 7 and Firefox 3.0.6, and I’ve temporarily deactivated my other plugins, with still no luck. My Server settings are:
* Operating System : Linux
* Server : Apache
* Memory usage : 13.73 MByte
* MYSQL Version : 4.0.27-standard-log
* SQL Mode : Not set
* PHP Version : 4.4.9
* PHP Safe Mode : Off
* PHP Allow URL fopen : On
* PHP Memory Limit : 40M
* PHP Max Upload Size : 20M
* PHP Max Post Size : 8M
* PHP Max Script Execute Time : 50000s
* PHP Exif support : Yes ( V1.4 )
* PHP IPTC support : Yes
* PHP XML support : Yes
* GD Version : bundled (2.0.28 compatible)
* FreeType Support : Yes
* FreeType Linkage : with freetype
* T1Lib Support : No
* GIF Read Support : Yes
* GIF Create Support : Yes
* JPG Support : Yes
* PNG Support : Yes
* WBMP Support : Yes
* XBM Support : Yes
* JIS-mapped Japanese Font Support : No
I don’t know if it helps, but this problem never appeared before the last update.
