pastore80 on "[Plugin: NextGEN Gallery] Error 500 after updating to wordpress 4.1"

Hi, i have tried to upload my site in another hosting. (altervista)
I re-upload a backup of my database in new service hosting. (but i have tried also another old backup)
Also in the new hosting when i activated the plugin i have the white page with this error: Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 261900 bytes) in /membri/frammentiditoscana/blog/wp-includes/class.wp-dependencies.php on line 213
Now i am crazy!! :/
