@spike,
did you follow the previous suggestions?
If so and your problem remains, please pm me access to your backend as super admin in order to check it out.

Hi Katia,

Thanks for the quick reply, i'm impressed!  :)

It hasn't been solved, I can't give access to the backend as one site is a school I do the webiste for and the other is a client who doesn't want any other access provided.

I have been using your gallery pro for years now. It's been great, but just the last two times I have the same error message.

Permissions are fine.... I am on the same server as other installs so I know its not server, the template is not the issue as I have reverted to the default beez template.

The latest error message is...

The was a problem converting the source image.
There was a problem rendering your image gallery. Please make sure that the folder you are using in the Simple Image Gallery Pro plugin tags exists and contains valid image files. The plugin could not locate the folder: images/stories/gallery/main_gallery/

I have cleared, turned off and restarted cache. Cleared my local cache... and nothing... here is the link

What SIG PRO and joomla! version do you use?

Joomla 2.5.6 and Sobi Pro 2.5.6...

Just upgraded to the newest version of Pro and it still won't work... had to disable link

I would love to help you but I need access to your backend in order to check your settings, permissions, conflicts...

I am also having the same issue on my site ( flackmemorial.com/index.php/about/history .  I have set permissions correctly on the folder/files and on the cache folder.

Katia helped me find out the problem - I had an image that was corrupt.  Once the bad image was removed all worked fine.  Hope this helps others!

Could you me with backend access to this site?

I have the same problem locally is perfect but I get this error on remote

We use the newest version of Simple Image Gallery Pro:: v2.5.8

Hopefully there is a way to fix this..?!
