GSgallery 2.0 - Simple Image Gallery Plugin (Square It)

[cumbe]

Hello;
Thanks for this great plugin!!!!
I have installed this plugin v2.5 stable release, and i have two problems:
1) When i save a gallery, show the message:

Code:

You don't have permission to access /Getsimple203/plugins/squareit-gallery/data/other/loadtab.php on this server.

This is not very important, because after the gallery saved works well.

2) And this problem that is driving me crazy!!!!
I don´t know because, but in some webs instead of display the thumbs, shows the code of gallery, for example {squareit_gallery_4d2209b8e5086}.
In all webs i have exec-php plugin. The code of gallery is in the content of page.
In that webs that doesn't display the gallery, if delete the exec plugin then the gallery is displayed.
The getsimple version in all webs is 2.03

Please if you know why happen it, comment it.

Thanks.

PD: I forgot to comment that use Fancy url enables.
Regards.
