Hello @reivilo007,
Perhaps it’s an existing conflict with another plugin or your theme.
Let’s check if it is an existing conflict:
– Temporarily deactivate all your plugins except NextGen Gallery.
– Is the problem solved? Then, it was caused by one of your plugins. Please check one by one and find the one causing the problem.
– If the problem is not solved with the deactivation of the plugins, try changing to a standard WordPress theme, it could be a conflict with your current theme.
If the problem persist, you might need to remove and re-install NextGEN Gallery.
Please, keep us posted, we are happy to help!
