MySQL missing tables

@klajo – Did you remove all other entries for NextGEN Gallery from the database?

This process will generally work but we recommend you have a complete fully verified back-up of your site just in case you run into any problems:

Use FTP to remove NextGEN Gallery related folders.
Then use something like http://wordpress.org/plugins/wpdbspringclean/ to delete all the ngg tables.
Then use something like http://wordpress.org/plugins/database-peek/ to search through the remaining tables for NGG references.
Then use something like http://wordpress.org/plugins/edit-any-table/ to delete all of these database entries.

Tables typically involved: wp_ngg_*, wp_options, wp_postmeta, and wp_usermeta

Thanks!

@klajo – What changes have occurred on your site since you last installed NextGEN Gallery without issue until your changes to the site/database and the plugin would not install as expected? This might also require you work with your web host to insure no server environment changes have been made as well.

Thanks!

@klajo – Updating the PHP, MySQL, and Memory limit should all help to improve performance of the site as well as NextGEN Gallery. The only thing that comes to mind from this information is possibly the process you used to do these updates (particularly the MySQL update). Did you insure all the previous privileges, permissions, etc. remained the same as they were prior to the updates? For example, does you WordPress database user still have *ALL* privileges?

Thanks!

@klajo – You would likely be best checking with your web hosting service’s technical support team to insure your current server environment is set correctly for a robust WordPress installation. You can specifically ask them to check your database user privileges while doing that.

Thanks!
