Hello, I've got a problem with album preview pictures.
WordPress up to date? - yes
NextGEN up to date? - yes
MySQL up to date (5.2.4)? - yes
PHP up to date (5.0)? - yes
The mod_rewrite Apache module activated? - yes
PHP Safe Mode OFF? - yes
and if you're willing to share:
Who are you hosted with? - webd.pl
What theme are you running? - free theme movie star
Which plugins do you have installed and activated? - statsurfer, w3 total cache, wp-polls
Does this error still occur if you switch your theme to the WP default, and deactivate all plugins except NextGEN Gallery? - yes, twenty ten and twenty eleven and only ngg plugin active.
My problem is that I can't choose album preview picture. I have two galleries in my album and both of them had thumbnail set (see screenshot).
I click to edit album but when I try to add preview picture, there is loading circle and nothing happen (see screenshot).
I even try in firefox, IE, chrome and opera but is still doesn't work.
I was looking for another topics with that problem, but nothing helped me:
