I am using v 1.9.18 of Nextcellent and I am finding that the permalinks for galleries are not ‘holding’. I have to go to Permalinks in the WordPress Settings and press ‘Save Changes’ for them to start working again. They seem to work for a while and then when I come back to the site the next day, say, they don’t work any longer. I have ‘Recreated URLs’ a few times in Nextcellent’s settings, but this doesn’t bring a permanent solution. Permalinks for regular WordPress pages are fine, it’s just any permalink that starts with ‘nggallery’. (it redirects to a 404 page when I try to access a gallery).
I thought it might have something to do with my .htaccess file’s permissions. (I use iThemes Security but have the file set to 664 rather than the more stringent 444), but even if I set it to 775, I still have to re-save the Permalinks in WordPress to get them to work again.
Is there anything else I can try or is anyone else having this problem?
