Indexhibit Support

Hi guys, after spending a couple hours on the forum I still couldn't find a relevant resolution for my issues. I've upgraded to 2.x and imported everything from the old database but there are still problems (btw I've followed the tutorials).
I'm the admin for this site: williammackrell.com

Problems so far:
1) "Warning...function.getimagesize", which I managed to fix by editing each exhibit like Vaska recommended
2) Settings, Assets, Plugins and Users tabs (admin panel) don't work - I get reverted to my homepage?!
3) Cannot Create exhibits, or upload images or change any options because of the broken popup window (I've tried 3 different browsers)

Please help!
Cheers, J

1. Visit each exhibit from the studio and it will regenerate the images.
2. Ask your host to disable or modify mod_security.
3. Is related to #2.

Let us know how it goes... ;)

Brilliant! Thanks for the quick response Vaska.
I'll open a ticket with the host and ask them to investigate the "mod_security" bug.
I'll post back with the outcome :)

Yup, the host has disabled mod_security and everything is running fine now.
Cheers

Great!
