Title: Nextgen gallery thumbnails uses http instead of https Last modified: July 24, 2020 --- # Nextgen gallery thumbnails uses http instead of https * Resolved [bitsum](https://wordpress.org/support/users/bitsum/) * (@bitsum) * [5 years, 9 months ago](https://wordpress.org/support/topic/nextgen-gallery-thumbnails-uses-http-instead-of-https/) * NGG uses HTTP (instead of HTTPS) image links in its thumbnail gallery. This causes an insecure content warning since HTTP images are interspersed on the page. * This is resolved by use of NGG’s Misc Options ‘Clear Image Cache’ button. However, it, at some point, reverts to previous behavior of HTTP links. Note that it is in a fixed state now on the affected page, so you won’t see it. * A user previously mentioned it [here](https://wordpress.org/support/topic/nextgen-gallery-uses-http-links-instead-of-https/)( and probably the post he referenced). However, your support incorrectly closed his request, assuming it was some SSL config error. * It is also mentioned [here on an SO question](https://stackoverflow.com/questions/43070424/nexgen-gallery-wordpress-https-update). That is where I got the tip to clear NGG’s image cache. * Other than NGG, which I hope to deprecate in the future, especially after this issue as well as [this one](https://wordpress.org/support/topic/simple-lightbox-crashes-in-new-version-3-3-6/), there is little other third-party plugins and no caching plugins that would interfere. * It seems purely an NGG issue. Please look into it.

Most of the time problems with SSL certificates are solved by using a plugin like “Real Simple SSL” [https://wordpress.org/plugins/really-simple-ssl/](https://wordpress.org/plugins/really-simple-ssl/) * That will force the whole WordPress install to use https links only. Note: this will fix mixed content issues as well if you have any. * Thread Starter [bitsum](https://wordpress.org/support/users/bitsum/) * (@bitsum) * [5 years, 6 months ago](https://wordpress.org/support/topic/nextgen-gallery-thumbnails-uses-http-instead-of-https/#post-13583518) * It isn’t related to the general SSL/TLS configuration of the server, or certificate. * Sometimes, bizarrely, NextGen chooses HTTP instead of HTTPS .. For instance, the below. I haven’t nailed down why this is happening sporadically, it seems odd, but am about to patch the gallery.php to replace HTTP with HTTPS. * `
