Just upgraded to the Beta 9.9.0 and had some problems.
If it helps anyone....after I'd upgraded, I was getting an error about sidebar_stories_wrapper.tpl' does not exist in.....etc.
This is because I was using my own template instead of the default yget. To fix the problem I just copied sidebar_stories_wrapper.tpl from templates/yget to templates/mytemplate
I'm still getting a problem as my Admin settings cannot be changed anymore. It just doesn't allow me to change config settings.
Ok this problem is discussed here:
Can't edit anything in Admin Config
But I've tried changing the htaccess.default to .htaccess with no effect. Except....
Now I'm getting an error:invalid username or userid in get_avatar
on my homepage at the right hand side. And none of my news is showing.
I can't get into my Modules management in the Admin because I get another error:
Your template is not compatible with this version of Pligg. Missing the 'clear_modules_cache' function in admin_modules_center.tpl.
I also cannot change my template back to the yget default because I can't change anything in the Admin settings. Catch 22.
