'/i'; $content = preg_replace($regex, '$1' . MULTPLE_DOMAIN_DOMAIN, $content); } return $content; } ``` * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fworks-perfectly-with-http-but-not-https%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * Thread Starter [Tony Law](https://wordpress.org/support/users/lbtdev/) * (@lbtdev) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11189071) * I have worked on this a little more and the issue only presents on Chrome now. All other browsers are fine. I have tried clearing my cache but it has had no effect. Please advise. * Thread Starter [Tony Law](https://wordpress.org/support/users/lbtdev/) * (@lbtdev) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11189224) * Tried on a fresh instance of Chrome and it worked, so this appears to be a caching issue with the individual browser. Looks like it’s working fine now. * [donPablo](https://wordpress.org/support/users/nook86/) * (@nook86) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11255369) * hello i have written email to you 🙂 - This reply was modified 7 years, 3 months ago by [donPablo](https://wordpress.org/support/users/nook86/). * Plugin Author [matthias.wagner](https://wordpress.org/support/users/matthiaswagner/) * (@matthiaswagner) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11255477) * [@nook86](https://wordpress.org/support/users/nook86/) looks like that email has disappeared somewhere in the net 😉 anyway, please use the forum for your questions. if it is http/https-related, chances are pretty high you will find your solution in the existing threads… * [donPablo](https://wordpress.org/support/users/nook86/) * (@nook86) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11255632) * i have send 😉 * hello sir * i found your site via [https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/) * ki have a question [http://www.wastepackgroup.co.uk/](http://www.wastepackgroup.co.uk/) really works on one installation [only normal qordpress tables and all content in wp_posts?] and really this multidomains works? does it have ability to change themes? i look for something like that to make easy my sites administration i dont have time nowadays :)) * btw you got log in possiblity there i can bet cookies does not work between domains? * and btw why you needed wildcard ssl for [https://www.wastepack.co.uk/](https://www.wastepack.co.uk/)? i dont see you use it with that multidomain installation just seprate domains with normal ssl’s without wildcard? * Plugin Author [matthias.wagner](https://wordpress.org/support/users/matthiaswagner/) * (@matthiaswagner) * [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11257628) * [@nook86](https://wordpress.org/support/users/nook86/) i can not follow your explanations and did not receive any emails either. the plugin will do exactly what is described at [https://wordpress.org/plugins/multiple-domain-mapping-on-single-site/](https://wordpress.org/plugins/multiple-domain-mapping-on-single-site/). * if you are not sure, try it out before you ask cryptic questions. no further answers will be given here. * matt Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Works perfectly with http, but not https’ is closed to new replies. * ![](https://ps.w.org/multiple-domain-mapping-on-single-site/assets/icon-256x256. png?rev=1595238) * [Multiple Domain Mapping on Single Site](https://wordpress.org/plugins/multiple-domain-mapping-on-single-site/) * [Frequently Asked Questions](https://wordpress.org/plugins/multiple-domain-mapping-on-single-site/#faq) * [Support Threads](https://wordpress.org/support/plugin/multiple-domain-mapping-on-single-site/) * [Active Topics](https://wordpress.org/support/plugin/multiple-domain-mapping-on-single-site/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/multiple-domain-mapping-on-single-site/unresolved/) * [Reviews](https://wordpress.org/support/plugin/multiple-domain-mapping-on-single-site/reviews/) ## Tags * [SSL](https://wordpress.org/support/topic-tag/ssl/) * 6 replies * 3 participants * Last reply from: [matthias.wagner](https://wordpress.org/support/users/matthiaswagner/) * Last activity: [7 years, 3 months ago](https://wordpress.org/support/topic/works-perfectly-with-http-but-not-https/#post-11257628) * Status: resolved
