Hi @fatimakyle
Apologies, we haven’t been able to replicate the same issue with our last version.
Could you please check if you have the recent version of our plugin?
You can also try to remove and re-install the plugin to avoid any file corruption during a recent update.
If the problem persists, we do recommend performing a conflict check:
1.- Temporarily deactivate all your plugins except NextGen Gallery.
2.- 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.
3.- 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.
Please let us know how it goes.
