Title: Permalink in notification mail sometimes with https Last modified: August 22, 2016 --- # Permalink in notification mail sometimes with https * Anonymous User 13545031 * (@anonymized-13545031) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/) * This week a user told me, that he gets a warning when accessing our site via the link in the notification email. * After some research I found out, that the link to the daily post was preceeded with https:// instead of [http://](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/?output_format=md). Since our hoster uses a shared certificate, a user gets a warning when accessing the site via SSL. * As far as I can remember the links to our post were http:// links only, otherwise this would have happend a lot earlier. We are up and running for about 2 years and are doing all regular updates of the plugin. * The next day the notification email went out with an http:// link, today’s mail was https:// again. * Any idea what this could be and how I could force non-SSL links? * Thanks, Georg * [https://wordpress.org/plugins/subscribe2/](https://wordpress.org/plugins/subscribe2/) Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/page/2/?output_format=md) [→](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/page/2/?output_format=md) * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432820) * @ansiman / Georg, * Are you using SSL for admin or any SSL plugins? * Thread Starter Anonymous User 13545031 * (@anonymized-13545031) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432927) * [@mattyrob](https://wordpress.org/support/users/mattyrob/) * No SSL for admin (though maybe I should…). After I noticed the issue, I installed the “Force non-SSL” plugin, but it didn’t do the trick.

Strange that this is not consistent. Have you checked for plugin conflicts because I have never encountered this before. * [Web Design Cheshire](https://wordpress.org/support/users/coderra/) * (@coderra) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432940) * Hi Mattyrob. * I have a site that also runs this plugin. I received an email today saying the same as ansiman. Subscribers have received emails with https rather than http. So they get a browser warning. * Permalink settings are normal (postname) and the site is non https. * Is there a fix for this issue? * Many thanks. * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432942) * [@coderra](https://wordpress.org/support/users/coderra/), * Can you list your current plugins so we can perhaps compare with @ansiman to see if there might be a common conflict. * Also, are these emails coming from ReadyGraph or direct from Subscribe2? * [Web Design Cheshire](https://wordpress.org/support/users/coderra/) * (@coderra) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432943) * Hi Mattyrob. * The emails come straight from subscribe2. It’s a strange one as most emails are http. Some then come as https. There is nothing different about the post from one to the other. * Plugins used: adcodes AddThis Social Bookmarking Widget Advanced Custom Fields Akismet Awesome Weather Widget BruteProtect Display Widgets Flickr Photostream Google Analytics by Yoast InfiniteWP – Client Quick Page/Post Redirect Plugin Recent Comment Avatars Simple Share Buttons Adder StatPress Subscribe2 Sweet Captcha Twitter Widget Pro Ultimate Tag Cloud Widget Wordfence Security Wordpress Ad Widget WordPress Importer WordPress SEO WP Category Tag Cloud * Thread Starter Anonymous User 13545031 * (@anonymized-13545031) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432960) * Here’s my list: Advanced Custom Fields Akismet CodeStyling Localization Configure SMTP Cron GUI Force non-SSL (doesn’t help) Google Analytics Post Thumbnail Editor Simple Optimizer Smart Archives Reloaded Stop Spammer Registrations Plugin Subscribe2 WP-Emoji wp-jquery-lightbox WP-Optimize WP-reCAPTCHA * as well as 3 custom plugins that I wrote, but none of them mess with neither mail nor permalinks in any way. * Our mails also come directly from Subscribe2. * HTH Georg * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5432992) * We can rule out Akismet, Configure SMTP and Stop Spammer Registrations Plugin as I use these and have never seen this issue. * The only common widget you are then both using is Advanced Custom Fields.

There is mostly only one post per day, scheduled to go online a 6pm. At 6.05pm a cronjob makes sure, that the post gets published. The notification email is then sent at about that time every day. Users can comment but cannot publish posts. * I will give the filter a shot and let you know. * Thanks for your continuing efforts!

There were just no notification mails going out. When I removed the code, the mails were sent again (the next day). Although I can’t understand why. The code just adds a function and two filters so this shouldn’t break anything. I put the code at the bottom of one of my custom modules. I’ll try the functions.php next. * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 6 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/#post-5433040) * @ansiman, * The code isn’t complete – my mistake and my apologies. After amending the content it needs to be sent back: * ``` function https_to_http( $content ) { $content = str_replace( 'https://', 'http://', $content ); return $content; } add_filter( 's2_html_email', 'https_to_http' ); add_filter( 's2_plain_email', 'https_to_http' ); ``` Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/page/2/?output_format=md) [→](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/page/2/?output_format=md) The topic ‘Permalink in notification mail sometimes with https’ is closed to new replies. * ![](https://ps.w.org/subscribe2/assets/icon-256x256.png?rev=2318630) * [Subscribe2 - Form, Email Subscribers & Newsletters](https://wordpress.org/plugins/subscribe2/) * [Frequently Asked Questions](https://wordpress.org/plugins/subscribe2/#faq) * [Support Threads](https://wordpress.org/support/plugin/subscribe2/) * [Active Topics](https://wordpress.org/support/plugin/subscribe2/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/subscribe2/unresolved/) * [Reviews](https://wordpress.org/support/plugin/subscribe2/reviews/) ## Tags * [HTTPS](https://wordpress.org/support/topic-tag/https/) * [permalink](https://wordpress.org/support/topic-tag/permalink/) * [SSL](https://wordpress.org/support/topic-tag/ssl/) * 18 replies * 4 participants * Last reply from: [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * Last activity: [10 years, 8 months ago](https://wordpress.org/support/topic/permalink-in-notification-mail-sometimes-with-https/page/2/#post-5433140) * Status: not resolved
