 * Hey,
   after i migrated my site, i get this error from NGG:
 * **RuntimeException thrown**
 * A_NextGen_Basic_Album_Urls does not exist.
   I replaced all url´s in my database
   but still not working. If deactivate the plugin the site works fine so i think
   it is safe to say its ngg causing the problem here.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fruntime-exception-url-does-not-exist%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@initiumit](https://wordpress.org/support/users/initiumit/),
 * This looks like a file integrity issue so let’s try deleting NextGen Gallery 
   plugin then installing it new to see if that’ll resolve the problem.
