After update to Gallery 1.6.2 I can't create/modify galleries

I'm using Revo 2.2.14, advanced installation.
I'm afraid there is some problem with files permission...

In the error.log I can't find anything interesting, with the browser console, when I try to create a new album i.e. I have the following errors:

Uncaught TypeError: undefined is not a function ext-all.js:7
create ext-all.js:7
Ext.extend.load modx.js:74
Ext.extend.createAlbum album.tree.js:39
Ext.applyIf.tbar.handler album.tree.js:10
Ext.Button.Ext.extend.onClick ext-all.js:7
I ext-all.js:7

does anybody can help me?
thanks!

Not seen this before but there have been issues with recent versions of gallery. Can you report this here: https://github.com/modxcms/Gallery/issues to make sure the dev is aware.

Thanks

You are right, I'll report it.

anyway I noticed that it happened to many of my sites, most of all I could solve with the "repair permission" tool of the hosting.

It seems that some file (i.e. assets/components/gallery/connectors.php) need to be executable, but I've not been able to specify the exact list of files involved.
