There’s a new version out with many bug fixes including (but not limited to)
- Some security hardening to media uploads
- Performance improvements
- Fixes for IIS6 support
- Fixes for taxonomy and PATHINFO (/index.php/) permalinks
- Fixes for various query and taxonomy edge cases that caused some plugin compatibility issues
You should upgrade as soon as you can – this sites been done, and of course that’s broken the access via the iPad application again.
I could just reapply the bodge below to get it working (kudos to NamesCo btw for commenting on the post) but not sure I’ll bother just now.
