I have purchased and configured the Simple Image Gallery PRO yesterday and installed it on my local wamp server that is a mirror site of the live version that is here:
www.gagneffiske.se

First of all I couldn't install the plg_jw_sigpro-v2.0.4_j1.5.zip from backend on the live site. So I put the whole site up by ftp and also uploaded the data base from my local wamp site and that did it.
The gallery started to work perfect.
Now I have added 2 more galleries on different locations on the site and but they didn't work. I then added them locally on the wamp mirror site and of course it worked like a charm. So i then uploaded all the image galleries including the labels.txt files all set.
Then updated the data base on the live site and whooops now all galleries are gone...
Noone works even though the SIG PRO seem to be correctly installed.

Why is this happening?
What can be wrong?
How do I solve this problem?

The url of your site seems not to be valid... ???

It works for me, strange...

gagneffiske.se/index.php/fiskebilder should work.

I got to update this as I have reuploaded all content from my WAMP mirror site to the live site and also imported the DB and voila now it works again.

But the main issue still remain, I can't install the plugin the nromal way and I still can't add new galleries by using the normal syntax for the SIG-PRO plugin:
{gallery}imagefolder{/gallery} it is as simple as this when working properly.
Haven't yet tested this as it now works on all galleries.
I have a theory for the misfunctionality to install and that is that my webhost has no options to disable safe mode in php.
Locally on my WAMP server it is disabled and works like a charm.

Would be nice to solve this issue...
