Since upgrading to 2.6 (and subsequently) to 2.6.1 and 2.6.2, I'm having a problem with images and captions.
Whenever I add a caption to an image, the saved Post displays an error similar to this:
Warning: Compilation failed: characters with values > 255 are not yet supported in classes at offset 16 in /vservers/username/htdocs/wp-includes/shortcodes.php on line 213
No matter how long or short the caption is, I get this error. I've never successfully been able to use captions. Any suggestions of what is wrong?
