Error prevents activation

Thank you for the heads up. I will check this out right now!

I have fixed the error which is thrown on php 5.4+. Thank you for pointing that out.

Also I have made some other usefull changes. Please check the readme changelog.

Would you be so kind to try out this version and let us know if it works for you now?

That was fast!
OK it seemed to have activated but it’s not shown under Tools.

Mhmm that is very odd indeed. That piece of code should be functioning as it is almost direct copy from the wikis ;).

Can I debug it on your site?

Sure, give me a contact email, I didn’t find any in the plugin description.

/update/
ok noted, you can delete it if you wish.

its opicron at gmail.com, thank you in advance!

It seems that your website has at least 40.000 attachments. The plugin worked successfully up to 23.000 attachments. This means I will have to break up some ajax call into smaller portions.

I will rewrite part of the plugin to accomodate for extremely large image collections. Please allow me to contact you shortly (weekend).

The plugin has finished indexing. Total uploaded media attachments 9999 (what a strange number). Total valid meta data entries 89965.

This was by far the largest dataset on which the plugin has run. Still the total index time is only about 30 seconds.
