re: The plugin was giving an php error earlier on but it is gone after deactivating it and activating it a few days later.
Hmmm, I had one other user report an error and after deactivating it and activating it again makes it go away. Unfortunately I have not been able to duplicate this error. I’ll need access to someone’s site while the error is occurring in order to track down and fix the cause.
re: The plugin also seemed to work earlier the day. I was now resorting categories and adding graphics to all of them, but now I am getting Fatal error: Call to undefined function wp_generate_attachment_metadata()
Ok, I think I know what the issue is. If you give me a temp admin account I will login and apply a hotfix to make sure the issue is fixed. The login details can be added here as a private reply.
