We are also having this issue on a client site and look forward to a solution or short-term workaround please.
All – This can commonly be due to a conflict with another active plugin, have you checked if that is the case?
– Cais.
It happens the minute I enable the “Automatically resize images after upload” feature. If I delete and reinstall the plugin without that enabled – everything works.
The theme is based on WP Foundation (Zurb) and I just saw lots of postings online about conflicts between the 2.
@cukeving – Thanks for this feedback, the Automatically re-size images functionality is a NextGEN Legacy option we have left in but do not recommend using.
We will have to review its continued inclusion, especially if it is now being reported as causing conflicts and issues.
– Cais.
PS: Did you just see this with your current theme, or were you able to recreate this with other themes as well? C.
